I can reliable reproduce this -- however, only with emacs21, not with
emacs22.

E.g. boot single user, shell=/bin/ksh
export TERM=vt100
emacs -nw a <ctrl-z>
man man

The man process will suspend itself after about half a second -- it's
not immediate, but very quick.
Putting it in the foreground again doesn't help -- the behaviour
repeats.

Cheers,
