Depending on $PWD, $TERM, etc isn't smart as they're controlled by
the shell and external sources and can be modified out from under you
(there's some recent discussion on the opengroup list that has
transpired related to $PATH, $PWD, etc).
How about this instead:
1. unset a predetermined env variable if it's present.
2. set it to a known value
3. Make sure that the env variable set in 2. matches both in the child
and parent.
If you submit this patch, I'll gladly commit it because it's more
sane than the current test code.
Thanks,
