well there's no builtin way of doing this, but i don't see why you
couldn't shell out and `monit restart ...` (assuming monit was
controlling your processes, replace as appropriate depending on your
deploying (eg touch tmp/restart.txt for passenger).
it's not very nice but would probably work. The obvious downside I can
think of is that if the administrator doesn't have shell access to the
server they could completely screw themselves without being able to
fix it (eg accidentally add a plugin that is broken or incompatible
with the app or the version of rails used)
