A minor nit: depending on who you ask, the phrase "green threads" is the
proper opposite of "native threads". Systems that utilize native threads
for scheduling (e.g. the Erlang SMP scheduler) are probably not properly
described as "green threaded". Prior to the SMP scheduler, Erlang could be
described as green threaded.

Erlang's creators prefer the phrase "process" for its concurrency
primitive, although it can generally be described as being "microthreaded"
