That's a bit problematic, because there's not much Dovecot can do about
it.. Another session has the mailbox opened and kernel keeps those files
open after deletion as .nfs* files that can't be deleted.

LAYOUT=maildir++ solves this by renaming everything under
~/Maildir/DOVECOT-TRASHED/ directory and hiding any errors about not
being able to delete .nfs* files. They are then deleted sometimes later.
But with LAYOUT=fs this isn't really possible, because such directory
would show up as being "DOVECOT-TRASHED" mailbox (not a problem with
Maildir++ because all mailboxes begin with ".").
I guess maybe the renaming could be done under ~/Maildir/tmp/ but that's
a bit ugly since it won't work generally with all mailbox formats..
All in all, currently this seems like too much trouble to fix.
