The cron 'export_process_queue' does not run as the false alarm server_busy

[Son Nguyen]

Version: master(15.04), 1.10

The function server_busy() does not take into account the number of CPU cores. That's why it often returns true on the server with many CPU core.

This postpones the cron 'export_process_queue'.
