As we provide a list of all objects that will be accessed from the batchbuffer, we can build a lut of the handles associated with those objects for this invocation and use that to avoid the overhead of looking up those objects again for every relocation. The cost of building and searching a small hash table is much less than that of acquiring a spinlock, searching a radix tree and manipulating an atomic refcnt per relocation.
