zwgc(1) says:
zwgc will exit cleanly (unset location and cancel sub-
scriptions) on:
SIGTERM
SIGHUP
XIOError (with a message to stderr)
SIGHUP is what it expects to get upon logout. Also, the
signals SIGINT, SIGQUIT, and SIGTSTP are ignored because
they can be sent inadvertently, and bizarre side-effects
can result. If you want them to be acted on, then run
zwgc -nofork &
What scenarious is it referring to, particularly with SIGQUIT?
There are times when I want to abort zwgc (like, for instance,
there is no zhm running and I've run zwgc) and its ignoring
of SIGINT, SIGQUIT, and SIGTSTP is really irritating. What's
the justification?
