Could it be better to add the __sizeof__() function to these types?
Python already has __sizeof__ and its not used for internal functions
so adding it would not break anything.
To copy pythons
int.__sizeof__(1) -> type(mesh).__sizeof__(mesh)
or in py 2.6 ... sys.getsizeof()
http://www.python.org/doc/2.6/library/sys.html#sys.getsizeof
Also interested in how your using this function.
