Catching user interrupts

Hi gang,

I'm running into trouble catching interrupts. It always works the first
time, but the second time I run a piece of code in the repl it becomes
unresponsive. For example:

(catch #t
       (lambda () (while #t #t))
       (lambda (key . args)
         (if (not (eq? key 'signal))
             (apply throw key args))))

Try that twice in your repl.

I've tried a lot more methods (sigaction throwing 'interrupt, sigaction
setting a system async to throw 'interrupt), but nothing works the
second time. Any clues? Thanks.
