    I agree that the vn_start_write() thing is not a Good Thing and it would
    certainly be desirable to get the entire snapshot thing into UFS/FFS
    where it belongs.

    Without digging through the entire issue, I would tend to lean towards
    the "catch them in the vop_*() which write" model on general principles.

Never attribute to malice what can adequately be explained by incompetence.
