while not tdl.event.isWindowClosed() hangs the console window about python-tcod HOT 3 CLOSED

Sorry, I was wrong. Nothing to do with setFPS. I should just add keyWait() in 
the and of the cycle.
First think, then create an issue.
Closed.

Don't worry about it.  Forgetting to call the event subsystem is actually a 
common beginner mistake with SDL.  I've even seen it happen in modern 
roguelikes where an animation or simulation (sleeping, worldgen) is run for a 
long time without checking for user input causing Windows to believe the 
program is hanging if the user clicks or hits a key during it.

I'm not sure how you're feeling about it, but I tend to be inspired by 
accidental feedback like this since this is actually a real issue that can and 
was triggered from normal use.  I already have the event module fine-tuned to 
work with modal environments so adding a simple call to tdl.event.get from 
tdl.flush could prevent the hangs in the examples I mentioned as well as the 
one you gave.

Or, you know, keyWait works fine too.  So I'll probably just put this idea on 
hold for a while.

Actually uploaded the fix.  I'll need to work on a lot of regressions before I 
can make a new release.
