This threadsafe class holds a mutable reference
to an object of type V and also holds a
mutable int value or
"stamp." It defines atomic
operations and volatile access semantics for the reference and the
stamp. This class works just like
AtomicMarkableReference except that an
int "stamp"
replaces the boolean
"mark." See
AtomicMarkableReference for further details.
