So df in btrfs is tricky at best, and relying on it for accurate information is
not great, but it's the best way to verify this test. So we need to add another
sync to make sure the pinned blocks are all freed up and the df space is really
really accurate, otherwise we end up with this test

I'm not quite sure why even 1 sync is needed. :(
I'm not sure what bug this is trying to test; if you need 2 syncs for global
space stats to accurately

Because of COW, we won't free up the
