Initialization of GKImagePicker hangs main thread.

[0xc00010ff]

This happens in the sample app the same as it does in my app.

Simply alloc-init'ing and presenting the view controller takes about 1 second, with the main thread blocked in the mean time. It's pretty clunky.

It wouldn't be too difficult to just send it off on a dispatch_async() and call back to the main thread when ready- but I think this should be covered GKImagePicker's implementation.

I'll test it in instruments and post info if I have time tomorrow.
