We've talked about this briefly before, but perhaps this should be the
default? I think that "child inherits the environment of the parent" is the
most commonly expected behavior; that's why environment variables are not
the same as command-line arguments. Programs which change context somehow
(setuid) should clear their environment before spawning a process, but in
general the child is running with the same permissions as the parent, and I
think it is appropriate for them to operate in the same environment.

I've got a patch to implement this around here somewhere..
