The new version of Feeley's Gambit (Scheme-to-C compiler) focuses on
making Erlang style threads effecitive (perhaps this was inspired
by Feeley's Erlang-to-Scheme compiler Etos?). As far as I understand
the only way to make process fast and process size small is to
implement your own thread switching in the runtime.
