Hi all,

just tried this in IDLE:

IDLE 1.1
 >>> import __builtin__ as bltin
 >>> bltin.True, bltin.False = bltin.False, bltin.True

 >>> ================================ RESTART 
================================

The restart was done by IDLE itself -- poor thing just gave up. So, it 
looks like Steve has found a `commit suicide' command for an IDLE 
shell :-)

Best to all,

Brian vdB
