    <para>
      The <application>NPth</application> package contains a very portable
      POSIX/ANSI-C based library for Unix platforms which provides
      non-preemptive priority-based scheduling for multiple threads of
      execution (multithreading) inside event-driven applications. All threads
      run in the same address space of the server application, but each thread
      has its own individual program-counter, run-time stack, signal mask and
      errno variable.
