Now deregistering is two step * process DisableReceiveHook then DestroyTransport. * 07/22/20000 rodtoll Bug #40296, 38858 - Crashes due to shutdown race condition * Now ensures that all threads from transport have left and that * all notificatinos have been processed before shutdown is complete. * 01/22/2001 rodtoll WINBUG #288437 - IA64 Pointer misalignment due to wire packets * ***************************************************************************/
