+SSH Key Agent Timeout
+-----------------------------
+``ssh-agent`` has an argument (``-t``) to timeout private keys. You'll need to
+enable this flag in your X initialization file somewhere... on Ubuntu it seems
+to be in ``/etc/X11/Xsession.d/90x11-common_ssh-agent`` (set ``SSHAGENTARGS='-t
+6h'`` for six hour timeout).
