I like the patch (it's quite clever!), except it would be nice if we
could avoid the p8/p9 dependencies.  Couldn't you restore r8/r10 after
.work_pending is done in if pLvSys is TRUE?  That way, .work_processed
would simply preserve (save _and_ restore) r8/r10.  My comments are
based on reading the diff only, though, so perhaps I'm missing
something.
