For comparison, Gambit Scheme takes about 1k per thread. Thread creation appears to stay under 3 microseconds as long as the heap remains abundant. These numbers are essentially the same as Erlang's.

Obviously room for improvement in CL if any of the providers take an interest in highly concurrent systems.
