As a follow-up to myself...
I've also found in init.c:init_signals() the following piece of code:
if (jobbing) {
long ttypgrp;
while ((ttypgrp = gettygrp()) != -1 && ttypgrp != mypgrp)
kill(0, SIGTTIN);
if (ttypgrp == -1) {
opts[MONITOR] = 0;
} else {
signal_ignore(SIGTTOU);
signal_ignore(SIGTSTP);
signal_ignore(SIGTTIN);
attachtty(mypgrp);
}
}
It's probably unnecessary and duplicate code in init_io() and should
be replaced by:
if (jobbing) {
signal_ignore(SIGTTOU);
signal_ignore(SIGTSTP);
signal_ignore(SIGTTIN);
}
Phil.
