It's probably unlikely to get many exploits as fixes will come through, but it's the impact of the fixes that will be the bigger issue.
If we start seeing stuff performing significantly worse after the fix, there will be some screaming. I've been reading reports of some software that have had up to 63% performance loss due to the change. Obviously it depends on the software and what people do, but if it hits something common like web browsers, media players, etc. then stuff might hit the fan...
