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