Loading Contacts app is slow
Here's the profile: http://people.mozilla.com/~bgirard/cleopatra/?report=AMIfv96ZzvY5KslavR9qViykPVb0SYPtJZ6OpTwKT4xCY4VmKM5X45h4w9Mvyj0n0kBbfu53EZR4pc4XugE6hjmaZoQ-oMNMLxkT9hu7kS56rbZY148qVJm46_b2fm8opoRxk-tkqpceoZ2PdIteRuyF9F49pfLCXg Things of note: - I've annotated OfflineCache stuff and it does seem to be responsible for the main thread sqlite io. - We spend a bunch of time loading hyphenation tables. (Do we need to use hyphenation?) - We spend time loading and sanitizing fonts - There's 192 ms of waiting time after the end of the animation I'm working on annotating some more to get a better picture of where more of the time is spent.

So, ah, the profile suggests that we're doing offline cache disk IO on the main thread. Please tell me that's not true.
I think offline cache is entirely on the main thread.
All offline cache SQLite IO is sync. FML. Will rewrite today with Thinker.

A couple of new things are now grouped together. e.g. TextRun construction, hyphenation, css parsing etc.
Should we close this bug now, or make it a meta bug for some more specific bugs (like there still is mozGetAll's lying in the facebook code) ?
