It does.  It _usually_ works fine.  The one problem is has is when lots 
of printing is being done by the script.

In this case, the first time you hit "break" the script will indeed be 
interrupted, but there will often be huge amounts of output queued up 
that will start being printed.  Sometimes you need to do a second 
"break" to kill the output being dumped.


A simple "while 1: pass" loop breaks just fine.  I have no idea why the original poster had problems, but probably the "print" issue, or some exception handlers in the script itself.
