For single thread use, subclass list, add a new .put method that checks 
the list size and either does self.append or self.sort(); process(list).

For multiple threads, you need the queue module, which has extra 
features (and baggage). A PriorityQueue yields items in sorted order. 
Subclass it and override .put to either call the original .put or start 
a process thread.
