I like this patch (I'm considering it for 2.0.7 - which
was feature frozen dammit ! :-), but I'd like to change
it to do the check in the timeout loop in main, not where
you currently have it which is within the main packet
receive loop.

The problem is it will add many become_root()/unbecome_root()
pairs to the main codepath if it isn't done in the timeout
loop, and these are *expensive* in performance (as Herb and I
found to our cost at SGI... :-).

Jeremy.
