In Python 2.4, retrieving sched's scheduler.queue class member would
return a time ordered list of events as expected. 

Since Python 2.5, the same operation retrieves a list of unordered
scheduled events. This makes it difficult to know which events are
really next in queue, especially if scheduled at the same time.

Raymond touched it last. :-)  Perhaps r38041 is to blame?

Looking at that change more, the queue is now maintained as a heapq. 
Perhaps the queue member is for internal use only?

Indeed, the queue is not directly exposed by a method, but the
information is nonetheless interesting for monitoring the content. If
it's not a bug, then maybe this could be changed to a feature request
for a new method to retrieve the queue's events.

Will add a method that returns an ordered list of events.
