It seems that sqlite on BTRFS is somewhat problimatic performance-wise.
See this blog post from Colin Walters where firefox was periodically
freezing due to sqlite, and apparently the database file was highly fragmented.
<https://blog.verbum.org/2020/07/14/on-btrfs/>
Mounting with nodatacow or autodefrag may help, or
`chattr +C .git/annex/keysdb/db`
Possibly being slow could explain the ErrorBusy: If there are somehow
two processes writing to the database and one is being slow, then
the other one could get ErrorBusy repeatedly for the 10 seconds it takes
git-annex to give up.
