This seems to improve the situation (still for the gas.py demo): In most 
cases, I can now just type ESC in one of the two output windows and it 
exits cleanly.

The problem is that this thing is not completely deterministic:

In the old (unpatched) version, most of the time typing ESC in the 
animation window would close this window but leave the bar-graph window 
open and the process resistent against Ctrl-C. Even hitting the 
bar-graph window with xkill would only kill this window, but leave the 
python process running and unresponsive to Ctrl-C. It had to be killed 
with kill from another shell.

In other cases (without recognizable pattern), upon hitting ESC in the 
animation window, it would empty that window but not close it and leave 
both windows unresponsive to attempts to close them. In this case, 
hitting Ctrl-C 3 times in the console window would kill the process and 
the windows.

With the new (patched) version, most of the time, hitting ESC in one of 
two output windows closes both and exits the process. Sometimes, it left 
the windows empty but open and unclosable. But then Ctrl-C worked every 
time.

In any case, the patch is now included in the updated Fink package.
