SubjectRe: process priorities
I am currently working on QNX-style scheduling for Linux 2.0.x that allows
much improved interactive performance under heavy CPU load. I expect to
release this patch this weekend sometime. I don't have SMP, so I'll be
looking forward to hearing how well (or *if*) it work with SMP.
