public class RmiSharedLockImpl
extends java.rmi.server.UnicastRemoteObject
implements RmiSharedLock

Requires a thread name to distinguish a non-hydra thread from a hydra thread with the same logical VM id, in case the enumerative JDK 1.5 thread ids and the logical hydra thread ids overlap (which is highly likely).
