I have no doubt that it's be nice to have. However, there are
practical difficulties with allowing that, and in particular a simple
enough device I added to try to support it doesn't work in a slightly
more complicated case. When this stuff fails, it is usually goes up
in smoke, and debugging that is not easy. So if someone has better
ideas, patches are welcome.
