Russ Cox also tells me that login works fine under his system. I
kind of expected that rc was working fine everywhere else.


And in the process of gathering the ps outputs to post here, I
just figured it out. Duh.

login has to be *execed*, not forked/and execed. So login is
a builtin shell alias for "exec login" in QNX's korn shell, so
login gets execed by the shell, the session leader and is happy.
I was trying to run login, so login was being execed by a forked
child of rc, NOT the session leader, and it was failing.

fn login { exec builtin login $* } seems appropriate here...
