Opening this since I've been working on improvements to the multiple precision
bits that should have positive effect here. In fact as I mentioned in comment
7, improvements are already evident.
Since optimization patches can go on forever, I'm going to put a cap on it for
the resolution of this bug. The cap is to implement findings of [1] if
applicable.
