Using GNU Emacs 18.54.1 of Sun Apr 30 1989 on ho5cad (usg-unix-v)

After bringing our 18.53 to 18.54 by patching in the diffs, we notice
the following behavior: hitting C-G kills subprocesses.  (We have
observed this with loadst as well as the emacs server.)

Am I right in speculating that this part of the 18.54 changes is
possibly to blame?  (Right at the moment, I don't have time to fiddle
with this.)

================================================================
+   * process.c (create_process):
+   On all USG systems, not just IRIS and AIX, don't pre-open pty's tty.
+   Move the setpgrp done for USG (no real change).
+   * callproc.c (child_setup): Don't do setpgrp on USG.
================================================================
[callproc.c]
! #ifdef USG
!   setpgrp ();         /* No arguments but equivalent in this case */
! #else
    setpgrp (pid, pid);
- #endif /* USG */
    setpgrp_of_tty (pid);

  #ifdef vipc
--- 374,381 ----
    close (err);

! #ifndef USG
    setpgrp (pid, pid);
    setpgrp_of_tty (pid);
+ #endif /* USG */
