Given the size of the counter, is it actually physically possible for a list to 
run out of room before the application runs out memory?

Even list(None for x in xrange(sys.maxint)) wouldn't do the trick, since each of 
those pointers to None is taking 4 bytes of memory, and Python's internal 
structures are already chewing up some of the address space.

Cheers,
Nick.
