----------------------------------------

Bela, can you make sure this is solved in next CR? We have a workaround in TEST_PING for this, but it'd be better to go with your fix.

> 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.
