Are there any tutorials or blog posts out there demonstrating how 
to use this? I think posts along the lines of "This is a 
CSP/message passing program in Go/Erlang. This is the same 
program translated into D; look how concise and faster it is!" 
could attract a lot of interest.

Reading the code in the pull request [1], for instance, makes me 
wonder how to tell if `spawn()` is spawning a thread or a fibre. 
Can a tid refer to a fibre? If so, why's it called a thread ID, 
and how do I tell if a particular tid refers to a thread or 
fibre? It would be great to have these kinds of questions 
answered in an easily available reference (for instance, the 
documentation for std.concurrency, which currently doesn't even 
mention fibres or vibe.d).
