  11 // = TITLE
  12 //     The Concurrency Bridge uses the Concrete Bridge pattern.
  13 //
  14 // = DESCRIPTION
  15 //     The Concurrency Bridge class plays the role of Abstraction
  16 //     in the Bridge pattern.  If the CONCURRENCY_IMPL is the
  17 //     base class JAWS_Concurrency_Impl, then it plays the classic
  18 //     role.  If the CONCURRENCY_IMPL is one of the Concrete
  19 //     Implementors, then its role is more that of an Adapter,
  20 //     which is like Bridge, but without the polymorphism overhead.
