--- Comment #1 from Damien Miller <djm at mindrot.org> ---
I think you have two options here:

First, you can explicitly shut down multiplexed sessions that have
stalled underlying TCP connection. E.g. I use

for x in ~/.ssh/ctl-* ; do test -r "$x" && ssh -Fnone -Ostop
-oControlPath="$x" dummy ; done

Second, you can set a protocol-level health check to automatically kill
unresponsive sessions. E.g. adding the following to ~/.ssh/config

ServerAliveInterval 2m
ServerAliveCountMax 3

Will terminate any unresponsive connection after six minutes.
