I'm trying to debug an event-driven framework I wrote myself and 
there are some iffy situations where a quick and dirty way to halt 
execution and view the state of some variables with print is to 
insert a while 1: pass (or sleep(0)).

The only reason sleep(0) is better than pass in my situation
is that when I try to do other things under the OS before I've 
had a chance to break out of the program, I don't get a slowdown.
