Fibers in C#: are they faster than iterators, and have people used them?

Question

So I was chatting with a colleague about fibers and turned up this paper from 2003 that describes a implementation of coroutines in C# using the Fiber API.

The imple

I haven't used it, but I have an interest in the subject. Here's one nice implementation of coroutines in C# with a round-robin scheduler: http://www.bluebytesoftware.com/blog/PermaLink.aspx?guid=71235c5a-3753-4bab-bdb0-334ab439afaf

By the way, quoting wikipedia, "fibers describe essentially the same concept as coroutines". As far as I know, the closest thing to a coroutine (or a fiber) in C# are iterators. Actually, they are remarkably close to coroutines. Lippert posted several catches about iterators. Hopefully, none of them represent an serious problem for the purposes you need.
