Yes, I think that those cases can be considered.  Some careful code
inspection will be needed to make sure the cases we want to enable are
safe, and some testing will be needed to make sure they behave
properly.  But it doesn't sound like an unsolvable problem.  I hope
someone who isn't me will decide to work on it.  :-)
