t3lib_div::getURL curl connection has no connection timeout
If you get content from a foreign server through t3lib_div::getURL in frontend and $GLOBALS['TYPO3_CONF_VARS']['SYS']['curlUse'] is true the content is fetched with curl. If the foreign server is down the TYPO3 page hangs till php max_execution_time is reached. I think this is not a good behavior.
I think the curl option CURLOPT_CONNECTTIMEOUT should be integrated by default.
For additional, it would be great if accessory curloptions are configurable or passable by parameter.
