There are options in between "immediate" and every half hour.

We also have regular changes that require restart.  We queue them,
and a job runs every 5 minutes and only restarts if there's something
in the queue.  The field people have to wait on average a couple
minutes.  This keeps the thrashing way down, since in our setup
there are sometimes dozens of requests within a minute or two,
and other times, none for hours.
