I don't have any idea why 1.16 would be causing something like this. Are
you sure something didn't change inside your process?

Anyway, yes. The closest from your earlier postings is:

so 6622 - 6408 = 214 revisions, and 388,846 - 51,993 = 336,853 / 214 =
1,574 changes per revision.

And then on to:

> Texts:        9040343 KiB  29%    453880 KiB  80%  1017118

(1017118 - 388846) / (7328 - 6622) = 628,272 / 706 = 889

Also, you can note that your "inventories" size went from:
19,270,232 to 19,979,626 to 21,696,982

Which doesn't look like it is increasing by much overall. (So it
wouldn't seem that you are adding a lot of new files.) But the
"compressed" size went from 25MB to 108MB, or almost 4x growth,
indicating that it thinks you have a lot of new entries.

Now, it is also possible that we have a bug. For example, what if
'heads()' was giving incorrect information, and causing us to generate a
new revision for texts that didn't actually need it. That would also
point to a lot of the other issues you've been seeing.

Certainly it is worth investigating. Though I'd also be curious as to
why we haven't been seeing this with other projects.
