Good. I just wanted to make sure that it's on purpose.

(I remember a system I worked with looooong ago. There was a stored
proecdure that filled up a table, and it was one long transaction.
Unfortunately, it tended to fill up the transaction log. (This was
Sybase 4.x, no autogrow.) My colleagues found the fix - they inserted
some COMMIT/BEGIN. Oh well.)

Well, that would buy you a transaction for the current and history table.
