For the short period of time that I was just logged in after your fix I saw at least 4 objects that were broke and were spouting grey goo errors. You need to take a little more time and think through this "fix". Just because something rezzes objects quickly doesn't classify it as an attack.
I have footprint attachments and flooring that rezzes small footprints as a person walks. Not an attack but all of those are now broken. I'm sure demo vendors that rez objects and many other objects will break due to this new code. Please rethink your solution. Slamming in knee-jerk response code is never a good idea.
