Yes, but it does. On seriousely inconsistent data -and zerofill is
seriousely inconsistent- it can behave bad. I think one almost cannot
code&catch every possible exception while still providing excellent
performance.

OTOH, I adopted ZFS very early for my database, and I am usually
running on scrap hardware, but it never gave me a real data loss issue.
