[Zope] Turn off Z2.log

How do I turn off the Z2.log logging? I am running Zope behind apache and I am using apache for all the logging. I have turned on STUPID_LOGFILE, so I really have no need for the Z2.log file. It is just a waste of processing power and disk space. The flags for the Z2.py file show how to change the location of this file but not how to turn it off. Thanks Tom
