OK, that's 6 changed messages for every out-of-order one (+ 3 index
files). That's still a lot less than "every single message in the
archive, every time".

Wouldn't that depend on how and why they're regenerated? If it's just
to add messages, then the same process could be followed, 6 old files
would be changed for each new file, and all the old files could keep
their message numbers.

What code? I didn't have any specific code, or algorithm, in mind. It
just seemed to me that inserting a message earlier in a thread
shouldn't be so much more trouble than adding it at the end. As I
said before, it's just:
1 -> 4 -> 2 -> 3
instead of:
1 -> 2 -> 3 -> 4
If it's more complicated than that, then there's something I'm not
understanding, and I'd appreciate it if you'd explain. Thanks,
Bob
