Python's recursion limit is too high for Mac OS X, where the 
default stack size is 512K. The attached script will never 
trigger a maximum recursion depth exception, it will have 
crashed Python with a segmentation violation before that.

A possible solution is a call to sys.setrecursionlimit() in 
site.py, another is to change the number "1000" in ceval.c 
to a configure-time constant.

Other platforms may also suffer this problem, it may be a 
good idea to add a test_stackoverflow.

I'm willing to do the work involved, but I'd like some 
feedback first.
