Still, this could have a really big impact, especially on filesystems
with slow fsck.

It'd be great to find a way to make this reliable.

It's kind of a historical accident that "test" is always mounted, but
"scratch" must be _required.  What if we added _require_test if we're 
going to write to test, and doing so triggers the check?

I'm sure there are other ways around it.  Spending tons of time in fsck
for a filesystem we didn't touch isn't time well spent, IMHO.
