The bug occurs when notify(n) is called while less than n threads are waiting in cond.wait(): when some threads didn't reach cond.wait() yet. The synchronization code is very fragile and depends on time. The issue was worked again in the master banch by adding more _wait() calls...

To really fix the race condition, reliable synchronization primitives should be used, like threading.Event.
