   Am I right in speculating that this part of the 18.54 changes is
   possibly to blame?

Almost certainly.  Since no setpgrp() is being executed any more, the
subprocesses are remaining attached to the pgrp where Emacs is
running.  Hence, since termio has ^G set to generate SIGINT, those
subprocesses are susceptible.  Put the setpgrp() back in and the
problem should disappear.

(I'd try it out myself, but I'm on the very edge of shutting down our
last SysV machine...)
