We need to do two non-trivial things with ttys -- interconnect slaves to masters (or to each other) and setup ctl-tty restoring task. Now this is done in subsequently depending on each other steps: 1. collect ttys 2. interconnect slaves and mark ctl-tty tasks 3. collect fake fds for tty-ctl tasks 4. setup orphaned slaves We can relax this logic in two ways: 1. don't split marking ctl-tty tasks and then creating fds for them do it in one step at the end 2. don't interconnect slaves with masters and orphaned slaves in two steps -- do it in one place after fds are collected Signed-off-by: Pavel Emelyanov <xemul@parallels.com>
