title: Unicorn workers' first responses are slower by few seconds
body: <p>I can't figure out how I can get my unicorn workers to only accept connections when they're really "ready" to process a request. I find that the first few requests are slow, then they speed up dramatically (from a few seconds down to a hundred or so ms). This problem seems to be compounded by the fact that unicorn seems to kill workers after a certain amount of time, meaning that I'm constantly facing the performance hit of the slow first request. Has anyone else seen this or have an idea of what I can do?</p>
