Description:
------------
(Error is from 0.9.10, $Revision: 298824$, but 11 changes in SVN since then don't address anything like this).

PHP's documentation for SolrClient::query says "Returns a SolrQueryResponse object on success and throws a SolrClientException object on failure."

So when trying to catch the error if the server is unresponsive, a try/catch should prevent the timeout errors from being viewed by users. For testing, I've been pointing the Solr client to http://reallyslowsite.com/x, where x is larger than SOLR_TIMEOUT. The timeout does occur, but I can't catch it.

Reproduce code:
---------------
$solr_options = array(
'hostname' => SOLR_SERVER_HOSTNAME,
'login'    => SOLR_SERVER_USERNAME,
'password' => SOLR_SERVER_PASSWORD,
'port'     => SOLR_SERVER_PORT,
'path'     => SOLR_PATH,
'timeout' => SOLR_TIMEOUT,
); 
$sc = new SolrClient($solr_options);
try {
	$query_response = $sc->query("lucene");
} catch(SolrException $e){
	echo "An error occurred.";
}

Expected result:
----------------
An error occurred.

Actual result:
--------------
PHP Warning: SolrClient::query() [solrclient.query]: Solr HTTP Error : 'Timeout was reached'...
