The company I must recently worked at would turn a zero day around essentially overnight as well. But we didn't like it, because something else got pushed aside for it. This will be somewhat more than a typical zero day because it will affect every class of device, whereas most zero days only affect certain classes or versions of devices. The original point was that you don't want to turn something like this into a last minute emergency by passing legislation that doesn't allow industry time to deal with it.
