------- Additional Comments from Nate Chapin <japhet at chromium.org>
Diff from last version:

CachedRawResources default to ResourceLoadPriorityMedium.  This matches the
existing behavior for DocumentThreadableLoaders.

CachedRawResource::data() protects the CachedRawResource.  The crash described
in https://bugs.webkit.org/show_bug.cgi?id=70388 was caused by the
CachedRawResource being deleted prematurely by the dataReceived() call.
