Axel Uhl a9706389b1 avoiding deadlock in mark passing calculator;

This is an aftermath to the loading of mark passings from the DB. If
mark passings with the correct fingerprint were found, the queue of
updates for the mark passing calculator is cleared using queue.clear().
This, however, may happen between the two synchronized blocks in the
Listen.run() method, after the queue was checked for isEmpty() and
before the queue.take() call is issued. In this case, queue.take()
will wait forever.

To fix this, the stop() method is called which will always insert an
endMarker into the queue so that the queue.take() method will at least
find that.
