No, after reviewing my notes, I don't think it is ssh after all. In
4.x, an ifdef'd out setsid (sshd.c:1402) leaves sshd subprocesses
 sharing the same `struct session' as the master sshd process.
However, the login shell or other commands that are executed will get
their own `struct session', so this is just cosmetic.
Still, I'd recommend removing that `getlogin' invocation.
