I've pushed this with some mostly-cosmetic adjustments:
* created a single subroutine that understands how to split DATA lines,
rather than having several copies of the regex
* rearranged the code so that the data structure returned by
Catalog::Catalogs() isn't scribbled on (which was already
happening before your patch, but it seemed pretty ugly to me)
* stripped out the bootstrap-time name lookup code from all of reg*
not just regproc.
There's certainly lots more that could be done in the genbki code,
but I think all we can justify at this stage of the development
cycle is to get the low-hanging fruit for testing speedups.
