Oh, blast, I thought I saw a patch (from you!) fly past many moons ago back around 2.6.0 that fixed the priority inversion problem, but if you say that it never existed, then my memory's obviously acting up :) it makes sense that it'd need to hook the syscall entry/exit path, at least to add one conditional, to implement the simple fix that _IDLE tasks are only _IDLE when not in the kernel...
If SCHED_BATCH solves the `my most backgrounded tasks eat ~5% of CPU time no matter what' problem, then good: that's what's really wanted by people running background compute-hogging jobs, after all.
