> It's hard to tell. If you compare yourself with traditional scripting languages like CRuby, CPython, JavaScript, Perl, PHP, Lua, … — they all use green threads as well.

"CRuby" (MRI) since 1.9 and "CPython" (forever, as far as I know) use native threads with a global runtime lock so only one thread running Ruby/Python code (but possibly more running native code in the same process) runs at any given time.

AFAIK, most JS environments don't provide threads (green or otherwise).
