Well, we enforce RLIMIT_RTTIME mostly because we can, not because it
would really inhibit all kind of RT-related misbehaviour of the clients.

Or in other words: RLIMIT_RTTIME is quite useful as a protection against
programming errors somewhre, however it is still easily circumventable
by people who really try to do evil things, unless combined with other
tricks, such as SCHED_RESET_ON_FORK.
