I think we got to the point where there was general agreement on the

For that, there's a good reply by Daniel P. Berrange, there:

From the libguestfs point of view, any sort of locking would be
preferable to the current situation. If someone wants to run with the
patch, I posted several versions and there was a lot of discussion on
qemu-devel in Nov/Dec 2009, starting with this message:
Subject: [Qemu-devel] [PATCH] Disk image shared and exclusive locks.
Message-ID:<20091204165301.ga4...@amd.home.annexia.org>
Aha, this is the discussion I were trying to find, but failed for
some unknown reason. Thank you Richard, I'm rehashing it all now...
