When the buffer state is reset after dropping messages, the mutexes are also reinitialized with new instances. This causes an issue with buffer_flush when it tries to unlock the new mutex that it never locked, raising Attempt to unlock a mutex which is not locked (ThreadError).
This fixes the issue by memoizing the buffer mutexes and reusing them even when the buffer state is reset.
