That's hard, given dovecot pointed at the same maildir: it quickly moves files from new to cur. That makes notmuch insert pretty useless, and I rely on notmuch new to approach correctness. 

But maybe I misunderstand: is the idea that it will return an error but keep processing?  Or stop on that error?
