I don'like them, at least not as substitutes for tasking. They can be a
way to interface and interleave two or more sequential algorithms in one
task, in a controlled way.

The proposals for "lightweight" tasks that I have seen have more
constraints and ugly limitations than I would like. Even Ravenscar
constraints are often annoying. Better OS support for Ada tasking would
be preferable. I'm not convinced that the best and fastest designs for
Ada tasking systems have been discovered yet.
