A two-in-one patch from the bugtracker

1) Fix some bad logic in the counting of statistics for QueueSummary manager event. Variables were not being
   reset for each additional queue, so cumulative totals were reported on each successive queue.

2) Add a longest hold time stat to QueueSummary manager event.
