I believe the Weitek 4167 (?) boosts 80486 fpt performance by "a factor of
3 or 4". In any case, how does the coupled 80486/4167 system decide which
fpt unit will execute a given fpt instruction? and is this a way around the
bug, temporarily - in that the Weitek would take over the sin/cos/tan stuff?
