Memory leaks below LoadLibrary

_From [timurrrr@google.com](https://code.google.com/u/timurrrr@google.com/) on June 21, 2011 08:49:43_

According to MSDN, http://msdn.microsoft.com/en-us/library/ms684175(v=vs.85).aspx "The system maintains a per-process reference count on all loaded modules. Calling LoadLibrary increments the reference count. Calling the FreeLibrary or FreeLibraryAndExitThread function decrements the reference count. The system unloads a module when its reference count reaches zero or when the process terminates (regardless of the reference count)."

If I got it right, there shouldn't be memory leaks below LoadLibrary (or they are benign).

However, Dr. Memory prints out memory leaks below LoadLibrary, e.g. on the issue #462 code:
