Swiftiply support for Thin

Looks like a I used an old Thin repos to make the patch - a lot of things have changed since then so I'll update the patch to the lastest repos revision.

Ok, here's the updated patch. At the moment I can get Swiftiply to do about 1226 requests per second, while nginx is around 5780.

thx Kirk, I'll wait for your feedback before applying the patch

post_init if @swiftiply

should be placed at the end of Connection#process not receive_data or else the request will be resetted at each packet received.

That might be the reason why it's slower then expected.

I did a quick benchmarks w/ a small rails app and perf seems very much the same:

nice -n20 ab -n5000 -c3 0.0.0.0:8080/simple

Swiftiply: 109.93 req/sec

Nginx w/ unix sockets: 108.13 req/sec

uh? I think lighthouse ate your comment or something kirk, you posted the ticket description.

I found out the reason for that performance problem (and am almost too embarrassed to admit to it). I was fetching the default index.html page, rather than doing a proper rails action. Nginx was configured for caching, so it served up that static page, while swiftiply was not. With that rectified I now get an average of 85.31 req/s for nginx, compared to 87.15 for swiftiply - which is very good for a ruby balancer. It's amazing to think that we can now deploy Rails apps with just a Ruby stack (forget about the C for the moment ;)). All anyone needs to get running is a couple of gems. They can even do the monitoring in God.

applied w/ some modifications, now on git master

thx a lot for the contribution Alex!

/me applauds excitedly!
