I appreciate the sentiment, but if you think about it... If a process can't be killed arbitrarily at any point during its execution then it's definitely not behaving in a "transactional" way (as in: sort-of-like-ACID-except-the-durability-may-not-be-that-important-as-long-as-consistency-and-atomicity-is-preserved). You really want processes to behave "transactionally", otherwise you'll be really really screwed when the power/UPSs fail.

(I'm ignoring the fact that a "kill -9" actually still flushes buffers and such, but that's tangential to the point I'm trying to make.)

EDIT: In summary: I'd rather find out sooner rather than later :).
