Grovel the tty structure using libkvm. You want to look for: (struct tty *)->t_pgrp->pg_id Which is the process ID of the group leader of the foregroun group. Or you could just make revoke do its thing in the right order instead of the wrong order, since a program with non-blocking fds (read: any threads program) would have to be clairvoyant (or check every time by trying to open /dev/tty, and noting when that failed).
