Ack. indeed. Nevermind my longer post then, getrusage() is usageless. (At least on Linux.)

A configure script test would be useful, but you'd have to build a minimal Python interpreter first to run the script, wouldn't you?

Nah, as long as you can test how many recursions it would take to run out of stack... But it's still not optimal: we're doing a check at compiletime (or rather, configure-time) on a limit which can change during the course of a single process, nevermind a single installation ;P And I don't really like doing a configure test that's just a program that tries to run out of memory... it might turn out troublesome for systems with decent sized stacks.

(getrlimit does work, so if we have getrlimit, we can 'calculate' the maximum number of recursions from that.)
