- Collector #1939: When running as a service, Zope could
        potentially collect too much log output filling the NT Event
        Log. When that happened, a 'print' during exception handling
        would cause an IOError in the restart code causing the service
        not to restart automatically.

        Problem is that a service/pythonw.exe process *always* has an
        invalid sys.stdout.  But due to the magic of buffering, small
        print statements would not fail - but once the file actually
        got written to, the error happened.  Never a problem when
        debugging, as the process has a console, and hence a valid
        stdout.
