Inactivity timer or inactive background processor. How does it work in SM 9.34?

Hello,  I've read about inactivity processor : "If using the SM applications version 9.32 or later, this process is obsolete. A new inactivity timer mechanism is used, which no longer requires this process.".  I would like to know which is the inactivity timer mechanism used in Service Manager 9.34 version.

Best Regards,
