You see. My memory is very short:) and I remembered that you were
working on gang blocks in ZFS boot code, but could find the commit, so I
went ahead with my changes. Those changes still didn't fix one problem
for me. Your patch seems to be much more complete and correct and it
fixes all my problems.

Please, wait no longer and commit your patch! We have to have this in 9.0.
