>Description:
When I stop an emacs21 process on the console, all processes started
later in the same shell (while emacs is suspended) also immediately seem
to get a stop signal.

>How-To-Repeat:
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 (man is suspended again immediately).

Looks like the stop signal sending is stuck :)

Not known.
