Not as yet - I'll try and find some time this week.

With the latest 4.2.x git, if I wait for each node to initialize before starting the next everything is fine: with an empty cache the time to start each node is in the order of a couple of seconds. If instead, I start two or more nodes at the same time, Infinispan seizes up for a much longer time. In the worst case I have seen Infinispan time out after 20 minutes. I can provide exact traces (I am not on my work computer at the moment), but I think that the rehasher should queue up other nodes while it is busy rehashing. This is quite a serious issue in my opinion and we should try and fix it before CR.
