Well, this seems to fix it:

'From Squeak4.4 of 1 March 2013 [latest update: #12489] on 6 August 2013 
at 3:39:29 pm'!

!Delay class methodsFor: 'snapshotting' stamp: 'raa 8/6/2013 15:22'!
restoreResumptionTimes
     "Private!! Restore the resumption times of all scheduled Delays 
after a snapshot or clock roll-over. This method should be called only 
while the AccessProtect semaphore is held."

     | newBaseTime |
     newBaseTime := Time millisecondClockValue.
     SuspendedDelays do: [:d | d adjustResumptionTimeOldBase: 0 newBase: 
newBaseTime].
     ActiveDelay == nil ifFalse: [
         ActiveDelay adjustResumptionTimeOldBase: 0 newBase: newBaseTime.
     ].
     ActiveDelayStartTime _ newBaseTime "<-----this"! !

Cheers,
Bob
