In situations where the operating system in in high disk I/O and many processes run into disk wait, the micro core seemed sometimes to register PING timeouts. That was simply due to the fact that the core itself was delayed and thought the PING packages didn't arrive in time.

This has now been fixed, by assuming that when checking the PING timeout taking into account the time since the last check: CMC assumes now that all PING must have arrived directly at the beginning of the current interval, not at the end.
