WriterPreferenceReadWriteLock.Signaller
extends Object
Reader and Writer requests are maintained in two different
wait sets, by two different objects. These objects do not
know whether the wait sets need notification since they
don't know preference rules. So, each supports a
method that can be selected by main controlling object
to perform the notifications. This base class simplifies mechanics.
