It is possible that such a reference map is meaningless in
the case of writing to a cache loader. It makes sense
streaming on the wire for an RPC call though. So maybe there
needs to be an overloaded form of objectTo|FromByteBuffer
that could disable the ref map?
Isn't that map used to ensure only a single copy of a
multiple-referenced object survives serialization? I'd think correct
behavior for that would be critical no matter where it's done.
