"One other audience member asked about running X without root privileges: that does work now, and Moblin is doing it. There are some problems remaining, though, especially with fast user switching. In the absence of a revoke() system call, there's no way to guarantee that one user isn't listening in on another."
Could someone expdand on the part in bold and describe in more detail what the problem is? Why would fast user switching cause a single fd to be allocated to processes belonging to different users?
