a race between updating and checking Max_used_connections.  This is done in
a loop until either disconnect finished or timeout expired.  In a latter case
the test will fail.


mysql-test/r/status.result:
  Update result to match changes in test case.
mysql-test/t/status.test:
  Close extra conections in previous test.
  In test for bug#15933 we have to wait for all disconnects to finish to avoid
  a race between updating and checking Max_used_connections.  This is done in
  a loop until either disconnect finished or timeout expired.  In a latter case
  the test will fail.
  Use con1, con2, con3 instead of con3, con4, con5.
