Surely, that the transaction operates in a predictable way?  A temp
table doesn't say, "I don't care about this data," it says, "I don't
care about this data over the long haul."  I've had lots of data go
through temp tables that I really really wanted to get into some other
place later, and it'd suck if the transaction failed half way through
because it turns out there's nowhere to put the data I've just staged.
