Rightly or wrongly, my goal is pretty clear.  I want to be able
to use file IO to control a daemon.  AF_UNIX doesn't help.
CUSE/FUSE takes over main() and makes it very difficult to use
select() and file descriptors.  So it fails too for now.

Yeah, if I proceed from here then modifying the user space parts
of FUSE might be the best way to go.

Sorry that it took so long to get to the point that my goals
for the patch were clearly stated.  As I say, I'm an EE who
probably need more adult supervision.  :)
