Perhaps what would be better would be a prompt module to modify xmonad's
environment at runtime.  Jamie's approach isn't truly general: if anything
happens to that ssh-agent, then you're up the creek without a paddle.  The
only approach is to do something like kill and restart xmonad from the
command line (or just restart X) in order to change the SSH_AGENT_PID
environment variable and the other one.  That's pretty ugly, and results in
losing all xmonad's state in either case.
