Review Comment:
@scwhittle you wer right when deserializing the same coder, we would get
different readers/writers.
I've fixed that in a way similar to the one you described, but maybe a bit
simpler. I've added a test for that too.
As curiosity, are coders serialized and deserialized often? my assumption
was that they this happens when a new vm is started for example, or when
checkpointing. or does it happen even more often so to have a performance
impact?
