--- Comment #1 from Darren Tucker <dtucker at dtucker.net> ---
You can do that via the ControlMaster's command option "-O".  It uses
the unix socket laying around wherever ControlPath points to.  It's a
security hazard so it's disabled by default, and it can only do a
subset of the things that ssh command line options support.

 -O ctl_cmd
       Control an active connection multiplexing master process.  When
       the -O option is specified, the ctl_cmd argument is interpreted
       and passed to the master process.  Valid commands are: "check"
       (check that the master process is running), "forward" (request
       forwardings without command execution), "cancel" (cancel
       forwardings), "exit" (request the master to exit), and "stop"
       (request the master to stop accepting further multiplexing
       requests).
