ThreadSafe::Util::Volatile#attr_volatile

Provides +volatile+ (in the JVM's sense) attribute accessors implemented atop of the +AtomicReference+s.
Usage:
  class Foo
    extend ThreadSafe::Util::Volatile
    attr_volatile :foo, :bar

    def initialize(bar)
      super() # must super() into parent initializers before using the volatile attribute accessors
      self.bar = bar
    end

    def hello
      my_foo = foo # volatile read
      self.foo = 1 # volatile write
      cas_foo(1, 2) # => true | a strong CAS
    end
  end
