There was a bit of a difference in philosophy between Mark and Raymond
as to how best to proceed with speeding it up (Mark's patch [1] focuses
solely on speeding up mantissa manipulation, while Raymond suggested a
more extensive rewrite in C would be preferable), so progress on the
issue stalled.

It would probably require at least a comment from Raymond saying to
proceed with the custom mantissa type approach to get that patch moving
again. Alternatively, if Raymond actually gets the project sponsorship
he mentioned a couple of months ago, that would also get things moving
again (just in a different direction).
