Sounds like an interesting calendar queue.  Lemme know how the  
performance is when you're done.  If the code's good we might add it

Note by the way that the key isn't necessarily just the time but also  
the ordering.  Make sure you'll do okay just basing the queue  
decisions on the time alone.
