There is no way for the kernel to accurately gauge the needs of a real-time application. Given a simple enough case, the developers of the application can determine what it needs, and require that users set the cap high enough, but in the general case, this is not possible.

No matter what the kernel does, if you want more CPU power than is available, you're doomed; all the isosynchronous patches do is limit the available CPU power to less than flat-out, allowing an admin to recover if a realtime process runs away. The solution is the same as in any other realtime system; get a faster processor.
