The two commits in this PR have their own commentary describing the changes that can be referred to, but to quickly summarize, this PR enables clean shutdowns of the reflector. The current code has no way of performing a clean shutdown for a couple reasons: (1) infinite loops in main() and (2) long blocking sleeps in various worker threads.
The general approach was to swap the blocking sleeps with condition variables that are signaled during shutdown, and to add signal handling in the main thread for termination signals. With these changes the reflector shuts down cleanly in less than a second with run as a daemon or in the foreground (when in the foreground, CTRL-C will initiate the shutdown).
