Is that a tongue in your cheek?

As far as I know there's indeed no parameter to control writes to temp space. So:
Avoiding the writes in the first place is the best option. Second best is making sure enough memory is available to accommodate for the operation, so no temp space is needed. Third and most likely option is a combination of the above.
