I stand corrected.
Except for the 2nd one, where I'm not quite sure what's going on, I'd
say I have yet to see the Python interpreter crash when doing "normal"
things not involving C esoteria (for some definition of normal not
including setting the recursion limit to 1e9).
Or maybe my total faith in Python to keep me from ever having to think
about memory problems when doing high-level coding is misplaced, but
I'd like to think not...
