Needs to be retested after jgroups 4 upgrade. Also, this is mostly a problem with stacks with TCP transport.

> Using the {{MERGE3}} protocol, it can take significantly longer than {{max_interval}} for merge to happen. 
> The info sender interval is up to 45 seconds
> {code:java}
>         public long nextInterval() {
>             return Math.max(min_interval, Util.random(max_interval) + max_interval/2);
>         }
> {code}
> and the view consistency checker interval is 48 seconds
> {code:java}
>     protected long computeCheckInterval() {
>         return (long)(max_interval * 1.6);

> which depending on the timing seem to take significant amount of time.
