> 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?
