The GHC's runtime system seems to have a pretty nice support for
multithreading. They are able to schedule N green threads over M OS
threads, where the scheduler can move green threads between cores
transparently. Of course they have it easier because Haskell disallow
mutable state, so they don't have to worry about locks.
Erlang's VM avoids locks as well by using shared-nothing threads and
message passing. Maybe a cool solution for Gambit-C would involve the
assimilation of Termite and further work on distributing the
lightweight processes among different cores. Incidentally, there may
be some work already done in that direction, given that for supporting
late binding on Windows modules don't access global variables anyway
and are half-way thread-safe.
Well, so far just a bunch of ideas anyway.
