Ryan Dahl 0ac2ef924f Do not spin on aceept() with EMFILE ...

When a server hit EMFILE it would continue to try to accept new connections
from the queue. This patch introduces a timeout of one second where it will
stop trying to accept new files. After the second is over it tries again.

This is a rather serious bug that has been effecting many highly concurrent
programs. It was introduced in 4593c0, version v0.2.0.

TODO: A test for this situation. Currently I test it like this

  termA% cd projects/node
  termA% ulimit -n 256
  termA% ./node benchmark/idle_server.js

  termB% cd projects/node
  termB% ./node benchmark/idle_clients.js

And watch how the server process behaves.
