-class RWLock:
-    """
-    Read-Write locking primitive
-
-    Synchronization object used in a solution of so-called second
-    readers-writers problem. In this problem, many readers can simultaneously
-    access a share, and a writer has an exclusive access to this share.
-    Additionally, the following constraints should be met:
-    1) no reader should be kept waiting if the share is currently opened for
-       reading unless a writer is also waiting for the share,
-    2) no writer should be kept waiting for the share longer than absolutely
-       necessary.
-
-    The implementation is based on [1, secs. 4.2.2, 4.2.6, 4.2.7]
-    with a modification -- adding an additional lock (C{self.__readers_queue})
-    -- in accordance with [2].
