Certainly for embedded "soft realtime" work I've found LTT really useful in understanding where the contentions where in my user-space code. And also why the old pthread mutex didn't work well with SCHED_RT priorities :-( If it was my choice I'd like to see LTT merged, but of course its not all about me much as I wish it was ;-) -- Alex, Kernel Hacker: http://www.bennee.com/~alex/ Assembly language experience is [important] for the maturity and understanding of how computers work that it provides. -- D.
