an overspill housing development
New towns were designed to house London's overspill.
Tents have been set up next to hospitals to handle the overspill.
It also operates a special bus on busy days which takes customers to and from its overspill car-park.
Some flooding from that overspill results-but not as much as if the spill were allowed to erode and destroy the levee itself.
You can change the buffer sizes to limit this overspill so that data is more readily available to the queue manager.
