[D-runtime] Update request from tango runtime

[Sean Kelly]

Oh the schedulers, related but different. It's a big change. Fawzi implemented that for some work he was doing. It seems a bit beyond the scope of what I'd intended for fibers, but I should give it a look. Fawzi, what do you think?

I'd not made the change until now because it could wreck performance in the normal case. I'll check out the post.
