* lisp.h, sysdep.c (block_tty_out_signal, unblock_tty_out_signal): New functions. * term.c (init_tty): Use them instead of rolling our own code. * sysdep.c (tcsetpgrp_without_stopping): Likewise. Here, this switches from 'signal' to 'pthread_sigmask', which is safer in multithreaded applications. * term.c (Fresume_tty): Don't bother dissociating if O_IGNORE_CTTY, which has already arranged for that. (dissociate_if_controlling_tty): If setsid fails, fall back on TIOCNOTTY. This is the main part of the bug fix. Fixes: debbugs:13387
