ChangeSet
  1.2333 05/08/08 18:05:27 jimw@stripped +1 -0
  Avoid problems on shutdown by shutting down replication slave threads
  after normal connection threads. (Bug #11796)

  sql/mysqld.cc
    1.583 05/08/08 18:05:24 jimw@stripped +5 -1
    Move call to end_slave() after first loop through killing threads,
    to minimize chances of 'SHOW SLAVE STATUS' being called between the
    time the slave is shut down and connections are shut down.

# This is a BitKeeper patch.  What follows are the unified diffs for the
# set of deltas contained in the patch.  The rest of the patch, the part
# that BitKeeper cares about, is below these diffs.
