today, i babbled at the EU Bureaucrats and amazingly they listened,
they are incredibly well trained and practiced at summarising and
absorbing input and feedback, it was deeply impressive to witness.
as it started at 8:30 am however i spent the entire afternoon asleep :)

i did a little bit on the core, to try to allow the TestIssuer FSM to have
overlapping instructions: the idea of issuing a DIV followed by an ADD
is working well, the two instructions do in fact create a Dependency
Hazard and the wrong result is produced (which is, ironically, a good
sign)

in core.py, i will have to add a "capture" system of the incoming decoded
instruction, because unfortunately it is necessary to acknowledge
the "acceptance" of the current instruction before the previous
pipeline stages (fetch, decode) can be permitted to continue.
i.e. use an internal ispec() temp copy of the incoming data.
