 and suppose you unload 'B.dll', and unluckily enough, the cache
 contains the type allocated in B's image...

+"Also, in your case, the current code ensures that either type is

+Sorry if I'm misunderstanding, but isn't the problem that a
+GenericInst from B references a generic type from C (that gets
+allocated from C's mempool), and C was already unloaded (freeing it's
+mempool)? Thus when B tries to check if the type is in B (and access
+type), it's accessing freed memory?
