I suspect so, though w/o delving into the Erlang VM, in particular its
threading and I/O model, we cannot be sure. The VM typically uses as
many threads as there are cores, but there is a separate pool of threads
for I/O, so it's reasonable to conclude that under heavy I/O load the
load average can exceed the number of cores.
