zabbix checks are blocked when remote server is unresponsive

[375gnu]

Hi, we're using your plugin and it works fine but only when there are no network problems.
But when one server is down it (plugin) waits too long and blocks other checks so we have a lot of errors for other jmx checks.

I've tried to set timeout in script like suggested in http://stackoverflow.com/questions/12791025/how-to-set-request-timeout-for-jmx-connector but without any success.

Could you add timeout checks to plugin itself?
