So how does a multithreaded process get 458% CPU on a quad-core machine? :) (Really, I want to know; I thought thread CPU accounting was fixed in 7.x. Unless I'm mistaken, 4 CPU-intensive threads in a single process should account as 4 CPU-intensive single-thread processes; i.e. each could only take up to 100% of a core/CPU, accounting for NCPU*100% total).
