   * Notes from the MSVC++ manual:

   *          abort() will be called on return to the caller.
   *          abort() raises SIGABRT. The default signal handler
   *          for all signals terminates the calling program with
   *          exit code 3.
   *       2) A term_func() must not throw an exception. Dev: Therefore
   *          term_func() should not call pthread_exit() if an
   *          exception-using version of pthreads-win32 library
   *          is being used (i.e. either pthreadVCE or pthreadVSE).
