Thanks for your report. Tomas and I have worked over the past couple of days
on a fixup series due to a rare race condition which was found after extensive
longrunning testing. While hacking on that we identified what I believe is the
same bug you found and we have a fix for that, the patchset will be shared very
shortly (we am literally putting the final touches on it as I write this).
I'll compare notes and will if applicable incorporate your patch into it.
