in earlier versions of 2.6, the kernel patch to allow SCHED_FIFO for

everyone was incredibly simple. i recall kjetil posting a couple of

lines, at most.
whether this a security risk depends on which other parts of the

kernel android uses. on regular linux, its no longer possible for any

process to steal all the CPU time. there are files in the /proc/sys

filesystem that control the amount available.
note that patching the kernel in this way means that any process by

any user can get SCHED_FIFO so its hardly clear that this is actually

any better than using rlimits from a security perspective.
