Sure, you needed to do that because you included all the basic primitive
wrapper types and other stuff as custom objects. River already optimizes
these down to a very small number of bytes (1 byte for Boolean and Byte, 2
bytes for Short, etc., plus one byte in the case where there needs to be a
class descriptor).
Also, I believe I can squeeze more bytes out of your custom marshallers as
well - I'll look them over once Galder is done.
