It is possible that the "loop" has determined there are no pending
timers but then the insertion application is executing and is
inserting a timer. Once the loop is executing again it will sleep
as there was no timer and we will miss the wake-up until there is
another timer.
In Pharo the Delay>>wait for one second will not expire anytime soon
in a new image. Use the depedency handling so we can terminate and
restart the loop.
