How to produce the bug:
Enter vnews, then send a followup or a reply using the `r' or `f' commands.
Then exit the editor. One is now back in vnews. If one then stops vnews with
^Z, the signal will also stop the background processes (mailer, uucp, etc.)
that the mail or inews programs had invoked.
The way I fixed it was to modify the "reply" and "follow" shell scripts
to add signals 18, 21, and 22 to those ignored during the invocation of inews
or mail. Unfortunately I had to modify the Bourne shell to let it recognize
the existence the higher numbered signals. The change to /bin/sh is trivial
(and, I believe, should have been done anyway). Change MAXTRAP in defs.h from
17 to 33.
