When you are being unloaded, usually when
IOleObject::SetClientSite(NULL) is called

Are you saying you have a COM singleton? Bad idea. Instead of giving out
the same object to every client, create a separate object for each
client, and have them forward method calls to a C++ singleton (that is
not exposed to the clients directly). Then each COM object can take care
of its event sinks.

With sufficient thrust, pigs fly just fine. However, this is not 
necessarily a good idea. It is hard to be sure where they are going to 
land, and it could be dangerous sitting under them as they fly 
overhead. -- RFC 1925
