no there is a good reason *to* use the exact same pseudocode: it
reduces IBM's workload.

and also ours.

please find and read my earlier IRC comments about hypothetical
discussions that may take place with the IBM Hardware Architects.

don't try to "hide" things like that, it will not be well received,
it will be viewed as an attempt to deceive, particularly if someone
after spending considerable time (a) notices they are the same or
(b) finds these conversations online and sees a conclusion that we
attempted to deceive.

no, it is far better to make the point that has consistently been
made: we're *not* doing VSX end of story, we do expect under the
Anti-Trust provisions to be taken seriously from a commercial
perspective that we need the SFFS Compliancy Level at an adequate
standard... *without* poisoning SFFS by pulling in VSX infrastructure
in any way shape or form.
