Imagine we have two peers, master and slave, and it's controlling
terminal. With current code there will be two attempts to setup
controoling terminal -- at first for master peer and then for slave
peer. Usually programs setup it via slave peer in such case (but in
real I need more soficticated check here, I need to find a session
leader in tree and find which peer belond to it). This is a fast
fix for most of programs but one more will be done on top.
