I'm willing to take a stab at it, but to do that I need a way to

something. Can you share what exactly was necessary?
I don't recall exactly what I did anymore, and it was pretty fiddly
anyway. Upthread I suggested
Now that we know where the problem is, you could probably make it highly
reproducible by inserting a sleep of a few msec between the rename and the
second fsync.
so why not try that first?
Ah, right. I'll give that a try.
