In our case the problem statement was that we had an inherently single-threaded emulator app that we wanted to push as hard as absolutely possible. We gave it as close to a whole cpu as we could using cpu and irq affinity and we used message queues in shared memory to allow another cpu to handle I/O. In our case we still had kernel threads running on the app cpu, but if we'd had a straightforward way to avoid them we would have used it.
