d995f8a668 Fixes a concurrency error in groupcache. Previously, multiple Get 
requests could simultaneously result in a load().  Only requests that
enter singleflight Do concurrently would be deduped, so it was possible for
populateCache to be called multiple times for the same key.  That
would result in overcounting nbytes, and eventually leading to a
livelock where nbytes > cacheBytes, but there were no entries in the
cache.

505a8b21f5 Reduce allocations 
Store temporary buffers in a sync.Pool.

Create one httpGetter per peer when Set() is called so we don't
allocate a new one on each call PickPeer().

89ec0544ae consistenthash: replace linear search with binary search 
The binary search quickly out-paces the linear search, even for a small
number of shards and replicas.

38eed8b4ba Close body even if it got error http status. 
Otherwise, http connections keep open if server
returned error status (e.g. Get returned error).
