And we're just at the first version. Currently there is only
one global tasks variable, and more work needs to be done
to make that threadsafe. But first we'll play with that.

But I'm thinking of some more. It should be possible to have
microthreads that don't block with a real thread switch.
They would just move into another thread that is micro-enabled
and continue there. It isn't that easy, needs more care about
switching and recursions, but well :-)
