I agree -- we would need to have a mode on which it is "not on any
connection", to which we could switch on C-z.  If all connections are
busy, there's no way to create a new one otherwise.

It makes sense if we continue with the shell analogy: the shell prompt
is not any particular task.  Either there is a task running in
foreground (in which case we have no prompt, but we can press C-z to
suspend the current task and get a prompt), or there isn't (in which
case we have a prompt.)
