Properly run daemon script as external check

[Virtul]

Hi! I'm trying to find workaround for 30 seconds for external scripts limitation by running my python script as daemon process, the script utilizes python-daemon module and is trivial:

import time
import daemon

if __name__ == '__main__':
    print "ok"
    with daemon.DaemonContext():
        time.sleep(31)
        print "done"

however Zabbix (2.0.9) recieves only empty string from it.

Why does it happen? Did anyone anything similar? Please share your experience.

Thanks in advance!
