Surely, a OS would do that. But this is Windows here.
In similar cases in the past, I have observed that this really can 
happen and stumbled across legacy code that all of a sudden had 
duplicate singletons because of this. I am not entirely sure but I have 
reason to believe this is more than just a reference count. When I 
execute the script, for example, loading the DLL takes considerable 
time. It's quite a large application and pulls in a bunch of 
dependencies. It took at least 3 seconds executing the script I pasted 
into the picture. But you are right, I have not verified this. I will 
try to create a singleton in that DLL and access it from the script. 
Maybe I can compare the addresses and see if it really is two objects.

Cheers,
