I've never understood why a process that is behaving could randomly get

Doesn't it make more sense to simply return ENOMEM to the process requesting
memory, and let -it- deal with the problem?  The OS needs to keep reserved
enough stack, etc, to make sure it remains consistent.

But being killed arbitrarily by the OS is, well, rude. (!)

I must be missing something fundamental, as I know that the L-word OS also
kills arbitrary processes when it gets frisky and runs out of memory; in fact,
I had a web server running on the L-word OS, and when it killed a process,
it killed Apache!  Boo!
