Possibly. I downloaded a version and used it for reference.

Looks good. ThreadMgr is like Java's ThreadGroup. But since "threads" are
managed by Prothon the potential is there for allowing custom thread scheduling
by extending ThreadMgr objects. ThreadMgr could also have a proper "wait()"
method that allows a thread to suspend itself until all threads in a ThreadMgr
group have terminated. It would make sure the suspending thread is not
a member of the ThreadMgr instance to avoid deadlocks.

A final comment. Stackless channels have a way to send an exception. Will the
yield statement do the same? I used it when implementing the tasklet generator.
