continuing [ticket:2522]

a disconnect detect + dispose that occurs
when the QueuePool has threads waiting
for connections would leave those
threads waiting for the duration of
the timeout on the old pool.   The fix
now notifies those waiters with a special
exception case and has them move onto
the new pool.  This fix may or may
not be ported to 0.7.  [ticket:2522]
