What I had to do was pull your child_open_uid() out
into a test program of my own and put in file writes
after it changed the fileno's around.

I've found a reason but not a solution to my problem.
Debian sets exim4 to user.group of Debian-exim.Debian-exim,
and loses the capability to set the gid it appears. I've
got a query into the packager about it.
