This is deep within the library code, where we know we won't overwrite the cached buffer for an object. Using getCachedBytes saves a full array copy while fixing a thin pack and appending whole objects. The extra copy isn't so much an issue of CPU time as it is about creating unnecessary temporary garbage for the GC to clean up.
