Mark, should Zope's nt_svcutils/service.py also be changed to import
pywintypes first?  Its import block looks like this now:

import sys, os, time, threading, signal
import win32api, win32event, win32file, win32pipe, win32process, win32security
import win32service, win32serviceutil, servicemanager
import pywintypes, winerror, win32con

I had "funny problems" getting the Windows ZRS installer to register
the ZRS service on older machines, primarily the

     python.exe - Entry Point Not Found

     The procedure entry point
     ?PyWinObject_AsDEVMODE@@YAHPAU_object@@PAPAU_devicemodeA@@H at Z could
     not be located in the dynamic link library pywintypes23.dll

popup box on a machine with an older pywintypes23.dll in the system32 directory.
