org.jpox.util.ReadWriteLock

A simple read-write lock implementation. Multiple threads may lock using readLock(), only one can lock using writeLock(). The caller is responsible for coding a try-finally that ensures unlock() is called for every readLock() and writeLock() call.

A ReadWriteLock is recursive; with one exception, a thread can re-lock an object it already has locked. Multiple read locks can be acquired by the same thread, as can multiple write locks. The exception however is that a write lock cannot be acquired when a read lock is already held (to allow this would cause deadlocks).

Successive lock calls from the same thread must be matched by an equal number of unlock() calls.
