Yeah, I know that they're two different processes but I thought that the
agent and subagent communicated more.  I thought -- and perhaps I
haven't looked at this closely enough -- that on shutdown the agent
tells the subagent to save its persistent values.  Based on that perhaps
weak assumption, I thought it would also tell it to reread config.

Well, I was asking if the subagent code set up a signal handler for
SIGHUP.  I guess I see now that that's unlikely.

Huh?
