This simply turns off destruction of a condition variable in
CUDTUnited::cleanup(), which is actually executed from within the global destructor, if not called manually.The true reason as to why this destruction causes a hangup should be further studied. Currently this is simply blocked on Windows, which isn't the proper solution, but as this is a global object, destroyed just before the program exits, it can be temporarily tolerated.
