Here is a big problem with transaction support in MySQL driver: it simpy 
doesn't work :( sql_transaction_commit_s() function fails and MySQL reports
this error: You have an error in your SQL syntax. Check the manual that
corresponds to your MySQL server version for the right syntax to use near 
';UPDATE ...

Looks like mysql_query() chokes if query contains semicolon.

IMHO we must just use MySQL BEGIN/COMMIT/ROLLBACK and let users care
about transaction safety of their databases.
