This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

Under Solaris 5.8, on the console:
Start emacs 21.1 with
  emacs -q -nw
from, say, an xterm window.  Then do
  M-x shell  (my shell is tcsh)
Then do something that takes time to run like
  /usr/sbin/traceroute www.bbc.co.uk
Then type ^C^C  (which is bound to comint-interrupt-subjob)
  
I then see a shell prompt, but the traceroute process is still running
and producing output and shows up in jobs.

I first ran into this with other processes (Allegro Common Lisp
executed from the command line in the shell buffer) that read input.
The earlier processes that I thought I had killed were getting input that
I typed into the shell buffer.



Here are some things that "fix" this:
 1.  Evaluate  (display-time)
or
 2.  emacs -q  (when using Sun's window system)

If either of these is done, then the problem doesn't manifest itself.


I will be unavailable until April 30.
