> The JGroups subsystem needs optimal defaults out of the box, that are also good for derived products (e.g. JDG), both for protocols and thread pools.
> Use a bounded thread pool for the default executor
> core-size==number of members (32 for JDG)
> max-threads = 1.5*core-size
> oob should be queueless
