Sorry, I should have been more clear - in one of the code snippets it
looked as though it was calling CreateInstance() if-and-only-if the
QI() call failed. That is what *seemed* odd to *me* - FWIF - or maybe
just something clever.
<code>
if(f != NULL) {
rv = f->QueryInterface(aIID,aInstancePtr);
if(NS_FAILED(rv)) {
rv = f->CreateInstance(outer,aIID,aInstancePtr);
}
}

I think the factory object helps track the number of references
to the shared library/dll to help determine whether it is safe to
unload it from memory.
Anyways, pondering the latest info further.
