Currently, specifying a session and exiting simply throws away everything in progress without confirmation.

How I'd like this fixed:
Hot Exit should ideally be session specific, so when I Hot Exit from a named session (with no clients connected) and then open the session back up by name, it'll reopen my buffers and such via Hot Exit handling. Right now it simply throws away everything, there isn't a way to get it back.
