I'll make a first snapshot of my derivate of Lua that includes
coroutines in about 2 weeks.

I have to make some notes here.

My coroutine implementation is not system independent because it
uses C coroutines and these cannot be made with ANSI functions.

And about thousands of coroutines: that's where coroutines would
really shine.  Unfortunately, my implementation creates a fixed
stack for Lua and one for C for _each_ coroutine.  You can set
these sizes during coroutine creation but I would say, a total
of less than 4kByte/coroutine becomes ... hmm... dangerous *g*.
So, with thousands of them you get pretty heavy memory usage.
