That's too bad, re: the scheduling. It seems to be a quite universal problem, yet I haven't seen much effort spent on working on the problem. :/

Re: phoronix, I commented mostly because the site is .com and not .org, so I came to a parked domain when I clicked your link. :)
Also, I figured linking directly to the article will help the archives.
