GMS: if a member leaving takes a long time, it can get merged back into the cluster
-----------------------------------------------------------------------------------

                 Key: JGRP-1336
                 URL: https://issues.jboss.org/browse/JGRP-1336
             Project: JGroups
          Issue Type: Bug
            Reporter: Bela Ban
            Assignee: Bela Ban
            Priority: Minor
             Fix For: 3.1


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.
