Maybe a list of the struct members (as a char*). Or even a hash of  
the attributes and all cdef methods. Most of the time the struct size  
is good enough though (but it doesn't catch stuff like re-ordering  
fields or newly inserted cdef methods). This would only apply to  
classed defined in .pxd Pyrex/Cython.
