 Hi,
 
 I had many, many exchanges of email with Marko Zec concerning this
 issue; please keep it open.
 
 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
