    Description

      ByteBufferArray getMultiple()/putMultiple() creates a new Visitor each call. we can move that visitor out.

      also, ByteBufferArray.multiple() seems to be an hotspot, I tried to do some experiments using slice and read/write lock instead of a mutex, doesn't seems to change much. any thoughts?
