.1 s would be fine.  I've noticed that mtn add has a similar delay
after the list of skipped and added files is shown, and mtn commit
takes 1-2s after exiting the editor for the commit comment.   I suspect
it's something to do with reading or verifying the manifest that the
problem, and since the script does a separate invocation of mtn get
attr file for every file, this is what is slow.
