[Python-Dev] stack check on Unix: any suggestions?

It tells you how much stack you've got; it does not tell you how much
of that is actually in use.

My patch computes (or, rather, estimates) a start-of-stack for each
thread, and then saves that in the thread context.

It should work for multiple threads just fine. It tries to allocate 8k
on the current stack, and then catches the error if any.
