I just now put up new-and-improved versions of these
software tools, and a web page summarizing the situation.
See

Status:
*) Worst-case customization time: about a minute on my laptop.
*) Best case: Less than 1 second.
*) The best case is the typical case, if you are making many disks.
*) The checksums in md5sum.txt are properly recomputed.
*) Better usage messages, better comments.
*) The supporting tools are now more robust and more generally useful:
-- Hacking ISO 9660 images
-- Hacking md5sum lists.
Comments and suggestions are welcome.
