My take on this is something like:
#!/bin/bash
echo $$ > /var/run/sshpf-persitent.pid
cat > ~/.ssh/config << EOF
Host *
Protocol 2
ServerAliveCountMax 3
ServerAliveInterval 120
ExitOnForwardFailure yes
EOF
sshpf ()
{
ssh -M -S /tmp/3306.port.forwarding -o ControlPersist=yes -L
3306:localhost:3306 -N -f p...@jumphost
}
sshpf
while:
do
if ssh -o ConnectionTimeout=1 p...@jumphost exit > /dev/null 2>&1; then
sleep 120
else
killall ssh
sshpf
fi
done
exit 0
Though, it will require SSH v2 and Openssh 5.6 if you like to use
'ControlPersist'.

of course using GNU screen helps the session last even longer. ctrl-a
