There isn't any way to do this at present and adding the ability would
be a little tricky. The master server would need to maintain some state
for each connection that is active so it can apply the rules.

I have vague plans to get the listening server maintaining similar state
for another reason (to track and act on frequent abnormal terminations),
so the infrastructure might happen eventually.
