title: I hit the rate limit for twitteR even from the first request
body: <p>As I say in the title, I always hit the rate limit (supposedly) even from the first request. Therefore, I cannot download anything from twitter.</p>
  
  <p>Here is my example code in R:</p>
  
  <pre><code>tweets = searchTwitter('blabla', n=1, cainfo = "cacert.pem")
  </code></pre>
  
  <p>And I keep getting this message:</p>
  
  <pre><code>[1] "Too Many Requests"
  [1] "Rate limited .... blocking for a minute ..."
  </code></pre>
  
  <p>What could I try?</p>
  
  <hr>
  
  <pre><code>reqURL &lt;- "http://api.twitter.com/oauth/request_token"
  accessURL &lt;- "http://api.twitter.com/oauth/access_token"
  authURL &lt;- "http://api.twitter.com/oauth/authorize"
  consumerKey &lt;- "KEY"
  consumerSecret &lt;- "KEY"
  twitCred &lt;- OAuthFactory$new(consumerKey=consumerKey,
                           consumerSecret=consumerSecret,
                           requestURL=reqURL,
                           accessURL=accessURL,
                           authURL=authURL)
  twitCred$handshake(cainfo = system.file("CurlSSL", "cacert.pem", package = "RCurl"))
  registerTwitterOAuth(twitCred)
  tweets = searchTwitter('blabla', n=10, cainfo = "cacert.pem")
  </code></pre>
  
  <p>The code is the above. Without any apparent reason, I managed to download some tweets but sometimes I still keep getting this message.</p>
  
  <p>Moreover, I'm searchong for a string and I cannot find it although I'm 100% sure that it exists on twitter. I'm getting a message that no response was retrieved from the server.</p>
