At this point I have two ideas:
1) Initialize TLSKey in DLL_PROCESS_ATTACH branch of callback
2) Make all this callback stuff optional, because it is actually needed for very few cases. 
"Optional" means referencing it from a fake function, which users who need the feature should call 
or reference. Otherwise it is smartlinked away.
