Class AsyncKeyLock<TKey>

Extension of the AsyncLock that enables fine-grained locking on a given key. Concurrent lock requests using different keys can execute simultaneously, while requests to lock using the same key will be forced to wait. This object is thread-safe and internally uses a pooling mechanism to minimize allocation of new locks.
