TIL, using mtimes for tracking event orderings is a monumentally bad idea (queue the nodding UNIX-beards). Mtimes are in wallclock time which is not necessarily monotonically increasing. A user may adjust the time, an NTP daemon will continously tune the clock and so on. Instead, store an explicit generation number in each condition file, which will be monotonically increased by finit on each reconf.
