I might even make that the default - hopefully those old lock daemons
are getting less common.

no, the client hasn't done a lock operation. 

the only alternative I can think of is to not close the file at all if
any mapped locks are present and instead defer the close until all
locks are gone or all copies of the file are closed in this smbd.

it should be a pretty rare situation anyway.
