Yes, the implementation requires root, but the overall design is NOT
what forces this to happen. The changes in 3.x to 4.x are NOT what
caused the server to have to run as root. When I ran XF 3.x I had to run
as root: 4.x hasn't changed this or made it worse.

With a safe kernel interface in place, I see no reason why XF 4.x cannot
take advantage of it.

Anyway, there is more than one project out there working on this kind of
issue. GGI for example is trying to do this and for more than just X.
