Probably not main(), but PyInitialize() for sure.

Py_Initialize() isn't good enough -- I can put an upper bound on the difference between "min" and the top of the stack: I can't do so for the call to Py_Initialize(). Well, I probably can in some really ugly way. I'll have to think about it some more.

Sounds good. If getrlimit is not available, we can always fallback to some (yet to be computed) constant, i.e. the current state.

Well, since Guido asked for a non-portable Linuxish way, I think we can assume getrusage() is there.

Ah, in this case, we'll get a memory error after filling the whole disk with frames

Which is great! Python promises to always throw an exception....
