Looks like we're shutting down the process and the CRT is calling destructors for static objects. In the destructor for PSScavenge::_gc_timer we're trying to free some memory which calls in to NMT who attempts to take a ThreadLocal lock, and we end up hanging in WaitForSingleObject.

     if (initialized) {
        DWORD ret = WaitForSingleObject(lock_event, INFINITE);
