I bet it will be tempting to extend it for other uses. Just like it was for me 
:). It looks just like another cpu_*map and stuff.

We could emulate isolcpu= boot option (the only visible user interface) via 
cpusets I suppose. But I'd rather not.
Since we do not plan on supporting it I'd say lets get rid of it.
