Time to reconsider m:n or green threading options?

Seems to me lately all the super-scaling languages and runtimes getting
attention are based on m:n or green threads across multiple processes.
Given that kernel threads obviously can't scale up to the tens of
thousands of concurrent processes e.g. Erlang can handle, is it possibly
a good time to consider adding an m:n threading model back into JVM?
Forgive my ignorance about the history of threading in JVM...what I
remember is that green threads used to be the only threading model, at
least on platforms I used. I thought I'd heard that it was m:n at some
point as well. And I thought I'd heard that Solaris was actually m:n
internally at some point too. Too much noise floating around in this brain.
Thoughts? Here's another framework trying to solve the threading issue
with bytecode postprocessing, similar to how Rife already supports
continuations. Seems like there's definitely demand for this, eh?
