I've been reading a lot about COM and trying to catch up, but I don't
know exactly what I need to test.  My guess for what you're looking
for is to create some buffers and release them all the while keeping
track of the ref count and when the dll can unload.  Is this close to
what is needed?  Could you point me in the right direction concerning
documentation (should I get "Inside Direct X") or examples for the
tests.  Thanks a lot.
