My point is: Even kernel 2.4 is not preemptive, the latence should be very
why user space application with low nice priority
can't be effectively interrupted and holds the CPU
resource since all user space application is

If your process has got work to do and has a higher priority than other processes, it gets to run. If you don't want this behavior, don't give it such a high priority.

If you want low latency to do some quick high priority task, just do it quickly and relinquish the processor, instead of hogging it.

What are you trying to accomplish, anyway?
