[Zope] Turning off undo for zope objects?

I remember seeing a post a while back about disabling the undo feature for zope objects to prevent the data.fs file from becoming too big. I can't find the post and can't find anything on the zope site (I dunno good keywords to search for). Anyone know the command to turn off undo?
