You're postulating a scenario in which some snippet of code doesn't know
what the surrounding script/application likes for AUTOCOMMIT, but does
know enough about the context to know that it's not inside a transaction
block already.  That combination seems moderately implausible to me.
Anyone have an example where it'd really be useful?
