[ Clarification: here "module" is not just "the thing you insert with
insmod". In RTAI it's a mlock'ed user-level thing that has higher
priority than the kernel, and can thus trivially crash the system.
Whether it runs in CPL0 or CPL3 is immaterial at that point - a crash is
a crash, and I'm not interested in systems where I cannot debug the
thing that caused it ]
