I hadn't followed that discussion even though I'm subscribed to
zsh-users. I had a look at your initial message on the ML

That probably explains then.

xclip or xsel fork a background process in order to own the
CLIPBOARD selection. Having something else owning the selection
(by having another app copying some text) should terminate that
xclip/xsel and release your ssh session.

Even if you redirect their stdin/out/err to /dev/null,
that xclip/xsel command will have a connection with sshd's X
server wrapper open and will hold your ssh session.

I don't think there's much you can do except killing those

ssh man page:

The session terminates when the command or shell on the remote
machine exits and all X11 and TCP connections have been closed.

What you could do is run xclipboard on the X server. That tool
polls the CLIPBOARD selection to always be its owner, so that
the xclip/xsel never hang around for very long.
