[Twisted-Python] Disabling PB (de)serialization

[Nicola Larosa]

I'd like to make a PB proxy "transparent". It should be able to get
serialized data via PB without deserializing it, and forward it via PB to
another proxy, without having to serialize it again. The second proxy will
receive the data, and serialize it before sending it to the final destination.

Currently the data are serialized and deserialized three plus threes times,
and that's rather inefficient when dealing with large data.

How do I selectively disable (de)serialization in PB?

Lately there's an abundance of improvised censors, and suppliers of
free good advice. What's that, you're out of bad example? Ask again
your usual wholesaler, surely scarcity is just momentary.
