# base class for \Rainbows! concurrency models, this is currently used by
# ThreadSpawn and ThreadPool models.  Base is also its own
# (non-)concurrency model which is basically Unicorn-with-keepalive, and
# not intended for production use, as keepalive with a pure prefork
# concurrency model is extremely expensive.
