Please note that we're talking about deletions and renames *between* the
scandir(3) call and going through the results it returns, during a
single invocation of 'notmuch new'. On the next run, scandir(3) won't
return the entry, and we'll think it's gone.

(Of course, if you keep deleting/renaming files and running 'notmuch
new' simultaneously all the time, you'll hit this on some other files on
the consequent runs, but then you asked for it...)

BR,
Jani.
