Comment 1 for bug 739433

Python converts integers to long integers internally as they get bigger. Obviously there could be issues if this values is used in a c-style data structure or by a client that cannot handle larger values, but the referenced lines don't break.

For example, in a python console:
>>> int(2**100)
1267650600228229401496703205376L

If there were limits to the integer representation, that would have overflowed them.
