This is an interesting data point. I will incorporate it. In the
meantime, we really need to stay focused on facts and not jump to
conclusions.

We can evaluate whether you stick with Btrfs, pros/cons. Bugs like
this are really slippery. The #1 reason they don't get caught and set
free, is tester exhaustion. This is a reasonable outcome. People have
better things to do than debug stuff. But it's sometimes a necessary
effort because we really are at significant confidence in Btrfs
stability equivalent to other file systems, even though we're aware of
its fragility in certain bad failure cases like this one. The only way
it gets better is to persevere.
