Returns: TRUE on
success, FALSE on errors
sesam_commit() commits any
pending updates to the database.
Note that there is no "auto-commit" feature as in other
databases, as it could lead to accidental data loss.
Uncommitted data at the end of the current script (or when
calling sesam_disconnect()) will be discarded by
an implied sesam_rollback() call.
