To really break things, I think this should really be something like:

>>> exp = 2**31L - 1
>>> exp
2147483647L
>>> exp = exp * 15
>>> exp
32212254705L
>>> 1 << exp
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
OverflowError: long int too large to convert to int

Also note that Python can't print the value of your 'big' variable; it
gets a MemoryError.
