Summary: scheduler.empty() in module sched appears broken

Initial Comment:
In:
Python 2.5 (r25:51918, Sep 19 2006, 08:49:13) 
[GCC 4.0.1 (Apple Computer, Inc. build 5341)] on darwin

The sched.scheduler.empty() method appears to be broken.  Its implementation is:
  return not not self.queue
Which returns true when the event queue is *not* empty.

Other Python builds seem to have a correct implementation:
