r22418: Support running under launchd. We abstract the method of obtaining
sockets to listen on a little, because in the launchd case these are provided for us. We also add an idle timeout so that a daemon can exit after a period of inactivity. (This used to be commit fc8589a3371d396197fae508e563f814899c2beb)
