I'm admittedly shooting in the dark here, but remember that a successful
fork() call returns *twice*.  Just because the *parent* has returned
doesn't mean that the *child* has finished all the processing and returned
as well - it may be delayed by other kernel threads etc and still not quite
ready for tweaking.

It sounds like a variant of the race conditions we had a while back where
lots of programs blew chunks when we started having "child runs first"
semantics so children could run and exit before the parent was ready
for it?
