If I understood kib@ correctly, this is fixed in -HEAD by r253927.

It was not too difficult to prepare a releng/9.2 build with r254754
reverted (reverting the revert) and then applying kib@'s suggested
backport fix.

So far that is running on 9 nodes with no reported problems, but only
since last night.  We were hesitant to do the significant work
involved to push it out to dozens of nodes if nobody was going to
consider it for 9.2 anyway.

Thanks!
