Testing with device-mapper-test-suite on really fast storage uncovered
various races.  Joe quickly fixed these and I've folded the fixes into
the patch series.

v2 will be staged staged in linux-dm.git's 'for-next' branch (after
rebase) very soon.  But I'll respond with the full patchset again just
to help anyone who cares to review/respond on list.
