I believe that in the old LinuxThreads implementation the manager thread

no manager thread).
Some experimenting leads me to believe that both the main thread and the
manager thread must be of higher priority than the cpu hogging thread,
otherwise priority inversion issues occur.
I was fairly shocked that even a "kill -9" failed to work though...
