> Useful for clustered DeploymentRepository and for ensuring only one node accesses a web session or SFSB at a time.
> This will be different from the JGroups DistributedLockManager is two main respects:
> 1) Built on HAPartition instead of RpcDispatcher.  This is actually a negative, but I want this to be able to use the same channel the AS's HAPartition uses.  Perhaps I'll develop a separate API and an adapter implementation that directly uses RpcDispatcher to provide flexibility going forward.
> 2) Acquiring a lock requires a callout to a pluggable LocalLockHandler. This is to support more sophisticated interaction with the service using the lock manager.
> I probably won't use the two-phase approach the JGroups DistributedLockManager adopts either.
