We're both agreed there is a problem, and we came up with a patch that he's OK with, but we didn't reach full agreement on some other issues which have implications for locking, which have subsequently addressed by somebody else. I would like to come up with a patch for FreeBSD 10 and revive the discussion, but I'm busy for the next couple of weeks. (and also a test harness which demonstrates casses where the distributed code fails, which can be run at user level). Keith > Date: Thu, 01 May 2014 19:18:41 +0400 > From: "Alexander V.
