I used the Yahoo Groups REST api instead, which is allows for requesting
the messages by a simple id (which is a non-random incrementing id), no
need to crawl or perform recursive downloads, and it allows for download
resume, and incremental updates when new messages have been added.

I wrote something in Java to do it for me, and either Yahoo doesn't do
rate limiting on that API, or I now have a corrupt archive ;) (checks of
random messages haven't revealed issues though). In any case, I managed
to archive firebird-support in a few hours.

I will play around to see if I can do something fun with that.
