Ticket #271 - Slow shutdown when you have 100+ replication agreements

Bug Description:  When you get into the range of 100+ repl agreements, the shutdown
                  can take a very long time to complete.  This is because each agreement
                  is its own thread, and it takes awhile to notify all of the threads.

Fix Description:  While we are shutting down each repl agreement thread, we wait for a full
                  second to see if the shutdown worked, before continuing on to the next
                  thread.  This means its going to take a minimum of 1 second for each
                  agreement.  This fix just reduces the wait to 100ms from 1000ms.
