Good to hear! That patch is a gross hack, and definitely won't work for
every RAID 5 (numbers should change based on number of columns and
stripe unit sizes). However, I'm yet to have a failure on my system with
that patch applied.

If I can find some time, I'll have a shot at a real fix. Unless Greg
beats me to it.
