This sounds like an interesting solution. Just to double-check: I have 
two Python extension modules _Qt.pyd and _Cm.pyd and the first one 
needs the routine CmpObj_Convert from the latter one I can 
LoadLibrary(_Cm.pyd) and it will work both when _Cm.pyd has already 
been loaded through the normal import mechanism and when it hasn't, and 
a subsequent import will also work correctly?

That leaves one question: can I get at the filename from where _Qt.pyd 
has been loaded? Because I would need that to construct the pathname 
for _Cm.pyd.
