- Fixed <rdar://problem/
4651931> 1% REGRESSION on iBench HTML due to
repeated requests for non-existent favicon
An optimization to avoid serializing favicon data for missing icons had stomped an
optimization to avoid GETing a missing favicon more than once. The solution
is a happy marriage of optimizations, ensuring that we *retain* the missing
favicon's "i am missing" data without posting a notification or saving it to disk.
