 just checking, they're pre- a code-reorg, so will need some work to
get up and running again.  which is important.

InputTest assumes a fixed number of items per "lane" (number of
Reservation Stations), and can't cope with being set to a single RS (i
just tried).

i can do another code-morph that "cheats" a little, sets the number of
muxids to 2 and allocates values in turn, sending a dummy value
(0,0,0) if there's not enough.
