SH-3329 Cached scene loads slower than same scene with cleared cache.

A/B comparison with original code showed the newer issuing lower-priority
requests of the cache reader and some other minor changes.  Brought them
into agreement (this is cargo-cult programming).  Made the HTTP resource
semaphore an atomic int for rigorous correctness across threads.  I
swear I'm going to tear down this code someday.
