In general, no.  Only one processor can ever be executing in the Python 
VM at a time.  But if the COM objects you use are implemented in *say) 
C++ and Python is only driving them, then although Python will not 
execute on both at once, the objects themselves might.  Of course, if 
you are talking about implementing these objects in Python, we are back 
in the same boat.

It may be possible for you to use RemoteServer COM objects, thereby 
having each object in its own process, and this would execute concurrently.
