Use only one (static) (de-)serializer for (de-)serializing SOPs. 

That improves performance drastically, at least for Mono, as the
(de-)serializers can then be optimized (and won't use reflection anymore).
On my system, before this change de-/serialization took ~9s/9s, whereas
after the change it takes ~.5/.2s.
