Hello, i upgrade from 0.3.9 to 0.3.12 and problem raise up. FD growing up and when i see graph with http connections, they still going to up. Num of connections i get from:

server = http.createServer(express);
console.log(server._connections);

and result is here: http://grabberapp.com/ety45t (with 6000 users). FD count in version 0.3.9 was about 1 to 1 with online users (~6000 FD). In version 0.3.12 FD going up (last value was ~50000 and then i need restart server - max open files = 50000).

How many FD should by opened, when you have e.g. 10000 ESTABLISHED connections.
When i go down to version 0.3.9 FD ~ ESTABLISHED connections. In version 0.3.12 after few hours is 3-times greater and still go up.
