I did look at this a long time ago - it doesn't really work becaue the
mutex you propose then has to be dropped and taken in the sleeping parts
of each ioctl to avoid app problems and in some cases threaded apps
deadlocking.

I think Arnd is right on his approach to this, having tried the other way.
