As I mentioned to you in previous mail, this all changed in
7.x and 8.x.  So, yes it went away.

The gain from having this complication was not balanced by the extra 
complexity. Also, in the real world, since Linux has no comparable
abstraction, no software is being written to use it.

It is possible that one could write a scheduler that would implement 
it again but keep the differences isolated within the scheduler.

In 8.x the KSE threading library goes away for the same reason.
The 1:1 library becomes the base implementation.

If you have questions you can email me directly for more details.
