A very wrong conclusion.
It just means that tasklets are able to emulate microthreads.

In what sense do you think microthreads are more developed?
Since they are able to simulate a totally idiotic interface
like what threads have?

There is no diference but in the interface.

They don't try to be like threads in the first place, and they
are way more efficient by nature.

No, they are not atomic in the sense of tasklet's atomic.
They will probably become the fundamental building block.
But if not, tasklets are considered to be too complicated.
There will be a better and simpler base class in any way,
whether greenlets survive or not.

What does this question mean, please?
If you knew what a continuation is, you would
not ask, or you are a reporter.
And after your previous postings, I really doubt that
you don't know what you are talking about.

No need to post to my list if that's your problem.

thanks for your time -- chris
