There is no reason for each imgRequest to have its own nsCategoryCache for "image-sniffing-services".  One global cache somewhere should be enough; this would save churn on the observer service and related friends.

I'll probably get to this mid-august.

This should probably block 1.9.3; it's causing significant churn, both cpu and power.

This might be a Fennec blocker, and we'll reprioritize if so, but for now this isn't a 1.9.3 blocker.
