> We have a mockup to test only the client. If we want to include the network, without
beeing limited by the i/o, we don't have much tools.
> This coprocessor helps to test this.
> I put it in the main code as to make it usable without adding a jar...
> I don't think it's possible avoid the WAL writes in the coprocessors. It would be great
to have it to simplify the test with any kind of client (i.e. w/o changing the durability).
