      When JChannel.disconnect() is called, and the leave processing takes a long time (e.g. due to excessive CPU use and GC), then it can happen that the leaving node is merged back into the cluster.
      This occurred in the Infinispan testsuite which is run in parallel (high CPU contention).
      SOLUTION: after sending the LEAVE request, disable discovery, so MERGE2 won't discover us.
