Re: How does screen survive logout?

My understanding (not having looked at the code - someone correct me if I'm
wrong) is that it's split into two processes, effectively a client and
server.  When you start a new screen session, it spins up both, but only
the client is associated with the terminal.  So closing the terminal kills
the client (as it should); the server lives on because it never got the
HUP.  When you attach a screen, it connects to a running server.
