Rather than totally disabling the logging, inform it we're about to exit
so we can log messages over the exit cleanly too. This aids debugging. It
also avoids a race where the logging handler could still error whilst
shutting down.

Also remove a race window by notificing the handler of the shutdown
first, before triggering it. This removes a race window I watched in
local testing.
