Even though it would require a total overhaul of every filesystem
and the VFS layer, it doesn't seem to me that I could cheerfully
use Linux in a zero-fault-tolerance environment when the fs code
simply disowns the fs when it finds a single measly bad block...

The entire VFS layer is going to be overhauled in the near future, and
such issues will be considered heavily along the way.

(As a side note, in a "zero fault tolerance" environment, you wouldn't
buy disks which could ever report bad blocks, you'd use some sort of
RAID strategy, all done in hardware, all mirrored and parity checked,
where it's "bad block, what's that?")
