A patch was produced and committed to head by kib@ as r256211. I applied the same patch to releng/9.2 and have had the patched 9.2 running on two production servers for over a week now. All looks good. The patch has now been MFC'd to stable/9 by kib@ as r256590. Unless there's a good reason to keep this open, I think this PR could now be closed. Thank you kib@ and pho@ for your work on this. -- John Marshall
