This does not seem wise, since returning a file to a consistent state following a crash would be a 1:n fanout and therefore ambiguous. Much better to fix the problems another way... Article directory lookup too slow? ...Use a btree directory structure. Etc. They are probably also not considering record orientation, a must for MIME attachments or encapsulation of article header items not in 822 (which, from memory, only had a "newsgroups" and an "in-reply-to" line...). There is very little difference from a good "MIMEFS" and a good "NEWSFS".
