Question about lifetime of environment variables in job files

Umm, so you want to either auto-add a "printenv" at the end of that
script, or use ptrace to stop it before running _exit() / exit_group()?

Both seems like an ugly hack to me; on the other hand I, can easily see
situations where that would be useful.

Personally, I'd rather use a designated file descriptor, so that a
script could explicitly set an envvar with

	echo "env FOO=bar" >&42

That's at least a posixly-clean solution.
