Class that acquires, renews, and releases a readers lock that is local to the process.
This class implements the reader interface to canonical readers/writer locks. Multiple readers can hold the lock simultaneously when no writers have the lock. Alternatively, when a writer holds the lock, no other participants (readers or writers) may hold the lock. This class is a more general-purpose synchronization mechanism than SunOS 5.x RLocks. For example, it implements "recursive RLock" semantics, where a thread that owns the token can reacquire it without deadlocking. In addition, threads that are blocked awaiting the token are serviced in strict FIFO order as other threads release the token (SunOS 5.x RLockes don't strictly enforce an acquisition order). The interfaces for acquire, tryacquire, renew, release, etc. are defined in ACE_Token_Proxy. The semantics for ACE_Local_RLock are that of a readers/writers lock. Acquire for this class implies a reader acquisition. That is, multiple clients may acquire a lock for read only.
