I would send a patch but my first attempt didn't work... Can this be done? Maybe renicing the threads could help in environments where you have lots of UMLs running? Like having the kernel runnig at -10 and userspace at 19 and sigio at 19? Maybe this could make the "time" inside UML more consistent in high loads? Comments?
