Maybe you are right Michael, but there's another point; the table wasn't
removed, it is still there, only data are cancelled.
It's more, like a DELETE FROM ... not a DROP TABLE...
and, if another user inserts data into this dropped table,
the table returns with all data.
(Refer to my first bug-report on this matter),
and more; some times ROLLBACK restores both data and table structure. ;-)
