<P>
Queue is a definition of a data structure that may
 act as a queue - that is, data can be added to one end of the
 queue and data can be requested from the head end of the queue.
 This class is thread safe for multiple producers and a single
 consumer.  The next() method will block until there is data in
 the queue.

 This has now been modified so that it is compatible with
 the earlier JDK1.1 in order to be suitable for running on
 mobile appliances.  This means replacing the LinkedList with
 a Vector, which is hardly ideal, but this Queue is typically
 only polled every second before dispatching messages.
