大量数据插入mongo的时候发生了timeout异常，提示UPDATE失败：
PHP Fatal error: Uncaught exception 'MongoCursorTimeoutException'
with message 'cursor timed out
(timeout: 10000, time left: 10:0, status: 0)
MongoDB Support => enabled
Version => 1.3.4
phpinfo()
PHP Version => 5.4.11
尝试了以下参数，均无效，
array('connectTimeoutMS'=>30000, 'socketTimeoutMS'=>30000, 'wTimeout'=>30000, 'w'=>0)
求解.
