Recompiled my program. It now throws a "loop" exception (which the 
exception handler catches) instead of just dying.

(Curiosly, the exception handler itself then throws an exception saying 
"<stdin>: hGetLine: illegal operation (handle is finalized)". It worked 
fine before... anybody know about this?)
