First thing that comes to my mind is Thread.setPriority(), and then just let the different tasks run concurrently but with different priorities and let the OS take care of managing the system resources (which is its primary function anyway.)
Second thing that comes to mind is to keep a shared AtomicInteger that holds the number of running important tasks, and then let the unimportant tasks check every so often if the AI is below some threashold, and only run if it is.
