The bug could be that the filesystem mtime resolution is 1 sec (hmm what
is the resolution in database?), and 2 emails are delivered to one
directory during one second -- and at the same time notmuch new is scanning
emails and found only one of those. then no more emails are delivered to
that one directory for a while -- so notmuch new does not find those.

(now that I think of it that could happen to me :O -- just very improbable
(or not, `stat .` outputs Modify: 2022-02-12 22:47:19.550838056 +0200) --
have to check that timestamp resolution in database).
