title: Parse lib sends signup request multiple times
body: <p>If a user is registered by calling the following call once:</p>
  
  <pre><code>   private void signup() {
          ParseUser user = new ParseUser();
          user.setUsername("ola");
          user.setPassword("kari4ever");
          user.setEmail("ola@nordmann.no");
  
          user.put("phone", "650-253-0000");
  
          user.signUpInBackground(new SignUpCallback() {
              public void done(ParseException e) {
                  if (e == null) {
                      toast("Hooray! The user is signed up");
                  } else {
                      toast("signup failed \n" + e.toString());
                  }
              }
          });
  
      }
  </code></pre>
  
  <p>If the user already exists, the parse library repeats the HTTP request many times before the <code>SingupCallback.done()</code> method is called.</p>

  <p>Is this a bug?</p>
