Get multiprocessing.Queue to do priorities

Dear Jesse,
thanks for the hint.

I see you are already assigned to the FIFO bug 
(http://bugs.python.org/issue4999), so I won't burden you even more. 
Clearly, a reliable FIFO behavior of multiprocessing.Queue helps more 
than a priority queue, since it can be used to build one, so that 
should really be the first thing to fix.

In the meantime, I think I'll whip up a hack that uses sort of a 
bucket- strategy: fill up a prioritized heapq, and then, in regular 
intervals, unload its contents into a size-limited multiprocessing 
queue.

I'll post this as soon as it works.
