Hrm, so the parsing code is indeed quite complicated.  I suspect it
could be simplified if instead of trying to allocate just what's used it
was a bit more wasteful and allocated the biggest arrays we might need
but I'm not sure how much that'd really help so yeah, doing it the other
way around might be better.
