I've googled and searched through the forums but haven't found too much on how fibers are implemented.  How does yield return execution to the caller but then resume execution in the same place on the next call?  Also some information on how the fiber call stack works would be nice.  I'm assuming it allocates the stack on the GC heap.  If so, what is the default size and is that configurable?  Any information or pointers to resources that provide this information would be helpful.  Thanks.

See "Documentation of Fiber internals" inside

Exactly what I was looking for, thanks.  Would be nice if this documentation was published on the website somewhere (probably in the Fiber library documentation).

Might be wrong but did you mean this?

I don't see that documentation anywhere on that page.  That's where I looked first actually.  It may or may not make sense to include that doc in the api documentation, but I think it would definitely make sense to include it on it's own page that talks about how fibers are implemented.  This information is more about learning about fibers as opposed to how to use them (which is all that most people want to know).
