I've started running tmux in all my terminals automatically, and conveniently sharing a "master" session between them all.

Instead of running tmux directly, I have a small script which creates a session named TMUX-MASTER if it doesn't already exist, and immediately detaches it. All the clients that I actually interact with are created separately and automatically grouped with the TMUX-MASTER session.

To prevent my system from being clogged by dozens of detached client sessions, I rebound prefix+d to kill-session, killing the client session but leaving my TMUX-MASTER session untouched. Closing terminals while running these client sessions, however, still leaves my system cluttered with dormant client sessions.

I'd like to see if a "ephemeral" option (it'd need a better name) could easily be added to new-session, which would cause the created session to just die when it's told to detach, or receives the HUP signal. It'd simplify things a bit.
