Thanks for the report. This is indeed an annoying behavior.

socat also appears to have this misbehavior, though it can be avoided by
supplying the reuseaddr option to the listening socket. Looking at the
socat source, it appears that this is related to the SO_REUSEADDR option.
It's not clear to me if this should be implemented automatically for
every listening connection for redir, or if it warrants an additional
command-line option. I'm inclined to avoid additional command line
options (the UI is already too clumsy and ill-structured). Can you
think of a scenario where it would be a bad thing to have either of
these socket options set?
