Good question!  I hope (and am relatively sure; but it's just a feeling :^) )
that the death of a process (whether it be by "exit()" or a kill signal)
freed up all allocated memory on pretty much any system with a sense
of memory management.

You could, of course, simply say

  Minimum RAM requirements:  XYZ

  Running the application with less than XYZ free causes undefined results.


I love undefined results. ;)

Like, maybe if you say "ls -5aTanR0olz" will format your hard disk. ;) [*]

ME - This is a Luvisi-ism ;)  Well.. not the Satan part, but the format part
