Reverse ssh tunnel bound to remote socket reserves the socket address after disconnect preventing reconnecting

I suspect that the reason the socket is not removed from the UNIX
filesystem is because Linux (I assume) doesn't remove it when the socket
is closed. SSH probably does the same thing to create and to destroy
UNIX-domain sockets as it does for IP sockets, namely, create using
socket()+bind(), destroy using close(). Personally, I think it's wrong
that the close() call doesn't remove the name, but that's something
which is unlikely to change.
You are right, SSH could remove the name, however, as it doesn't
(although perhaps that might change), you could work around the problem
by removing it yourself, e.g.
sh -c 'ssh -N -T -R $(pwd)/lol.socket:127.0.0.1:4444 127.0.0.1; rm
