title: emacs slime can not connect to swank
body: <p>After I type <code>M-x:slime-connect</code> with emacs on windows7-64,and enter host and port: <code>host:127.0.0.1</code> / <code>port:4005</code>.</p>
  
  <p>It shows the error:</p>
  
  <pre><code>Connecting to Swank on port 4005..
  open-network-stream: make client process failed: too many open files, :name, SLIME Lisp, :buffer, nil, :host, 127.0.0.1, :service, 4005, :nowait, nil
  </code></pre>
