The real problem is that I'm doing a user-space scheduler, for education
purpose, and I need my scheduling thread to change the priority of threads in
other processes. But it seems impossible to do in an easy way. :( And yes it
have to be a real-time scheduler, because I'm studying real-time systems and
scheduling real-time systems.
Thanks
