[IronPython] Road to IronPython 2.7 (update)

[Tristan Zajonc]

It appears to be because int is a very large long.  This is probably the
core issue:

In IronPython:

>>> a=143098242404177361603877621312831893704
Traceback (most recent call last):
OverflowError: Number overflow.
>>> a=143098242404177361603877621312831893704L
>>> a
143098242404177361603877621312831893704L

In Python:

>>> a=143098242404177361603877621312831893704
>>> a
143098242404177361603877621312831893704L
>>> a=143098242404177361603877621312831893704L
>>> a
143098242404177361603877621312831893704L
>>>
