I don't know, but I've never had the impression that Erlang was
very quick to initialize. What happens if the clock is started
by triggering it inside an already running VM?

Also, I don't know how much it affects the benchmark, but sockets
basically behave like low-priority processes. This seems to work
OK in a system that handles large volumes of I/O and doing some-
thing significant with most of it (e.g. connection handling.)
