Fix for file_lock. The documentation and implementation did not match, and
the sleep gap was done even when using socket locking, making file locking with sockets
slower than required.

<h3>Version 0.9 / 2006-02-17</h3><ul>
<li>
The SQL syntax in the docs is now cross-linked
</li><li>
Written a parser for the BNF in the help file.
Written a test to run random statements based on this BNF.
</li><li>
Support function syntax: POSITION(pattern IN text).
</li><li>
Support for list syntax: select * from test where (id, name)=(1, 'Hi'). This is experimental only.
It should only be used for compatibility, as indexes are not used in this case currently.
This is currently undocumented, until indexes are used.
</li><li>
Function CONCAT now supports a variable number of arguments.
</li><li>
Support for MySQL syntax: LAST_INSERT_ID() as an alias for IDENTITY()
</li><li>
Support for Oracle syntax: DUAL table, sequence.NEXTVAL / CURRVAL.
Function NVL as alias for COALESCE.
Function INSTR as alias for LOCATE. Support for SYSTIMESTAMP and SYSTIME.
Function ROWNUM
</li><li>
Implemented a ROWNUM() function, but only supported for simple queries.
</li><li>
Implemented local temporary tables.
</li><li>
Implemented short version of constraints in CREATE TABLE:
CREATE TABLE TEST(ID INT UNIQUE, NAME VARCHAR CHECK LENGTH(NAME)>3).
</li><li>
Implemented function NEXTVAL and CURRVAL for sequences (PostgreSQL compatibility).
</li><li>
Bugfix for special cases of subqueries containing group by.
</li><li>
Multi-dimension (spatial index) support: This is done without supporting R-Tree indexes.
Instead, a function to map multi-dimensional data to a scalar (using a space filling curve) is implemented.
</li><li>
Computed Columns: Support for MS SQL Server style computed columns. with computed columns,
it is very simple to emulate functional indexes (sometimes called function-based indexes).
</li><li>
Locking: Added the SQL statement SET LOCK_MODE to disable table level locking.
This is to improve compatibility with HSQLDB.
</li><li>
Schema / Catalog: Improved compatibility with HSQLDB, now use a default schema called 'PUBLIC'.
</li></ul>
<h3>Version 0.9 / 2006-02-05</h3><ul>
<li>
Implemented function EXTRACT
</li><li>
Parser: bugfix for reading numbers like 1e-1
</li><li>
BLOB/CLOB: implemented Blob and Clob classes with 'read' functionality.
</li><li>
Function TRIM: other characters than space can be removed now.
</li><li>
Implemented CASE WHEN, ANY, ALL
</li><li>
Referential integrity: Deleting rows in the parent table was sometimes not possible, fixed.
</li><li>
Data compression: Implemented data compressions functions.
</li><li>
Large database: the database size was limited to 2 GB due to a bug. Fixed.
Improved the recovery performance. Added a progress function to the database event listener.
Renamed exception listener to database event listener. Added functionality to set
the listener at startup (to display the progress of opening / recovering a database).
</li><li>
Quoted keywords as identifiers: It was not possible to connect to the database again when
a (quoted) keyword was used as a table / column name. Fixed.
</li><li>
Compatibility: DATE, TIME and TIMESTAMP can now be used as identifiers (for example, table and column names).
They are only keywords if followed by a string, like in TIME '10:20:40'.
</li><li>
Compatibility: PostgreSQL and MySQL round 0.5 to 1 when converting to integer, HSQLDB and
other Java databases do not. Added this to the compatibility settings. The default is to behave like HSQLDB.
</li><li>
Synthetic tests: Utils / BitField threw java.lang.ArrayIndexOutOfBoundsException in some situations.
Parser: DATE / TIME / TIMESTAMP constants where not parser correctly in some situations.
Object ID assignment didn't always work correctly for indexes if other objects where dropped before.
Generated constraint names where not in all cases unique. If creating a unique index failed due to
primary key violation, some data remained in the database file, leading to problems later.
</li><li>
Storage: In some situations when creating many tables, the error 'double allocation' appeared. Fixed.
</li><li>
Auto-Increment column: It was possible to drop a sequence that belongs to a table
(auto increment column) after reconnecting. Fixed.
</li><li>
Auto-Increment column: It was possible to drop a sequence that belongs to a table
(auto increment column) after reconnecting. Fixed. ALTER TABLE ADD COLUMN didn't
work correctly on a table with auto-increment column,
</li><li>
Default values: If a subquery was used as a default value (do other database support this?),
it was executed in the wrong session context after reconnecting.
</li></ul>
<h3>Version 0.9 / 2006-01-26</h3><ul>
<li>
Autoincrement: There was a problem with IDENTITY columns, the inserted value was not stored in the session, and
so the IDENTITY() function didn't work after reconnect.
</li><li>
Storage: Simplified handling of deleted records. This also improves the performance of DROP TABLE.
</li><li>
Encrypted files: Fixed a bug with file.setLength if the new size is smaller than before.
</li><li>
Server mode: Fixed a problem with very big strings (larger than 64 KB).
</li><li>
Identity columns: when a manual value was inserted that was higher than the current
sequence value, the sequence was not updated to the higher value. Fixed.
</li><li>
Added a setting for the maximum number of rows (in a result set) that are kept in-memory
(MAX_MEMORY_ROWS). Increased the default from 1000 to 10000.
</li><li>
Bug: Sometimes log records where not written completely when using the binary storage format. Fixed.
</li><li>
Performance: now sorting the records by file position before writing.
This improves the performance of closing the database in some situations.
</li><li>
Two-Phase-Commit is implemented. However, the XA API is not yet implemented.
</li><li>
Bug: Recovery didn't work correctly if the database was not properly closed twice in a row
(reason: the checksum for rolled back records was not updated in the log file).
</li><li>
Bug: Renaming a table and then reconnect didn't work.
