Summary Iterate non-contiguous NSData regions instead of copying to contiguous buffer

CFNetwork gives us NSData which we then copy to SharedMemory, but we do so by calling NSData.data which copies the data to a newly allocated buffer in about 1/4-1/3 of the cases of my local browsing. Iterating using enumerateByteRangesUsingBlock instead removes this copy and allocation
