As far as I know, they don't work, i.e., they crash with internal
error. Both require sched_getaffinity (and maybe more) and that is
not implemented. I believe JDK breakage is serious blocker for the
2.6.16. Since we cannot support the syscall directly (i.e., we don't
have user process affinity), we may have to fake it.
