I haven't started with that one.

In general, I am not at all sure of WHY the C standard must decide this.
Thread libraries are working OK, and POSIX pthreads is widely used.

It would be better that the C standard would scrap all this and add
a line:

"The threads specifications follows the POSIX standard."

Microsoft has implemented it under windows, and some companies
have ported it to windows. Support from the C standard would
be a good thing.

But if they are going to do this, then let's do it right from the
start. Because if the specs are shaky, limited and primitive
nobody will use them and the standard will make a new failure.

That is the main worry behind my post.
