Review comment:
> This is also currently being done for active scans. So if it's an
issue with the fetch compactions thread, we should do something with the scans
fetch as well.
Yeah, I saw that. It seems like it's a problem there, too. I'm not sure when
that got added, but we definitely don't need the monitor constantly talking to
every server in the cluster every 5 seconds, if the monitor doesn't even have
any active clients requesting pages.
