Hot package uses maxint, incompatible with Python 3.4.

[Felipe Monteiro]

Currently, hot_package.py uses sys.maxint to compute the maximum and minimum integers. However, sys.maxint is not compatible with Python 3.4. Thus, when the code is run against Python 3.4, an AttributeError is thrown.

The following stacktrace is produced:

Traceback (most recent call last):
