much of it is experimentation, i'm not very happy about the increased
size, however it's an unavoidable side-efffect of turning the original
code into (a) modules and (b) single-stage pipelines.
also, the vast majority of it really really needs to be split to a
separate shared python module.
i think the most sensible thing to do is for me to do fpdiv.py and
you to track that in fpmul.py. the modifications required are
let's start with using FPState?
