It looks like dovecot's interval is 10 seconds, so for this to work right, notmuch will need to call lockfile_touch() more often than that. /* How often to touch the uidlist lock file when it's locked. This is done both when using KEEP_LOCKED flag and when syncing a large maildir. */ #define MAILDIR_LOCK_TOUCH_SECS 10 As yet, I don't know if that's likely to be easy to add.
