It's not quite clear what happens there - I can reproduce this on my 
PowerBook, too. However, it's not really a show-stopper, because 
hitting <Esc> will give you console back and everything is OK again.

It's hard to tell if this is related to the timer (we're using a 
one-shot timer to start the REPL), or something else ... I'll keep on 
digging ...
