Lev,

I haven't forgotten about this issue.
Unfortunately, I can not devote as much time as I would like to it.
I revisited it again and I couldn't spot anything new besides what my old patch

https://docs.freebsd.org/cgi/getmsg.cgi?fetch=24428+0+archive/2016/freebsd-fs/20161106.freebsd-fs

I know that George [cc-ed] was going to work on this problem.  Perhaps, he has
something for you to test or debug.
