If they find an inconsistent stripe they don't try to identify the
corrupt block. Instead, they dumbly *recompute P and Q*, which of
course makes the stripe consistent, but *leaves the corrupt data in
place*.

I'm skeptical that MD would be so willfully stupid.  did you conclude
this from reading the code, empirical testing, or from the author?
to me, the code looks to be doing something sensible (it definitely
acts differently when the failure(s) are on P/Q/data.)
