Hello all!
I'm having a simple problem when using PyPy in windows 7.

My program which only uses 2 external packages (SimPy and networkx) and
which also works well under CPython 2.7.2, is throwing an AttributeError
Exception, when run in PyPy 1.9.

*Traceback (most recent call last):

AttributeError: 'Message' object has no attribute '__sizeof__'

Can anyone help me here ?
