Linus,

I agree that there may be some problem in the code above -- the question is
what has changed to make this behavior emerge? I see it with a host of
programs(ssh, make, netscape) -- true all are userspace. Time permitting,
I may attempt to track this down in ssh and make in jobserver mode. It
may be related to some interaction that changed underneath.
