Yup, give them time to fix it. Oh wait, the fix causes it to be 10-20% slower! D'oh!
I wouldn't consider the current "fix" to be a real fix for the problem though. The current situation is like having a leaky sunroof in your car and using duct tape to solve the immediate problem until you get round to replacing the seal which is causing the problem. However, using the duct tape means you can't (quickly/easily) open the sunroof.
