Technically, why are processes in Erlang more efficient than OS threads?
...he entire CPU state (normal, SSE and FPU registers, address space mapping, etc.).
Erlang processes use dynamically allocated stacks, which start very small and grow as necessary. This permits the spawning of many thousands — even millions — of Erlang processes without sucking up all available RA...
