Looks good.  My test cases work as expected.  I added some DMDEBUG to
help debugging (will send as a separate patch in case we'd prefer to
drop it).

I've rebased it to work with a 'for-2.6.36' block change and the latest
discard patches that Alasdair recently queued.

I'll post v2 of your 2nd patch shortly.

Thanks,
Mike
