I can recreate it, but only for a give filename. That means the
filesystem has kept a kinked state for that file, and it cannot heal it.

The reason how it got to the kinked state is still obscure to me. I
suspect some race condition, but IMO the real bug is more that the
filesystem cannot recover on its own. 

The brick says:

Here is what I have in the brick:
