I don't think this should turn out to be a major problem.

The mutex is really there as a quick way of detecting the failure of an
existing mutex-aware hub.

In reality, because we are saying that only services should act as hubs
(due to the fact that they're running all the time), the mutex feature will
probably not be used a great deal.

The only difference is that if your Java framework is providing the hub,
and then is shut down, it will take longer for another application to
realise that the hub has failed.

Apart from this increased delay in re-establishing the existance of a hub,
I don't think there should be any major compatibility issues.
