A system, for use with a first application concurrently operating together with a second application, includes an activity manager and a communication processor. The activity manager intermittently receives data identifying activity associated with the first application, and determines that the first application is inactive in response to a first application timeout window being exceeded because of insufficient activity associated with the first application. The communication processor communicates to a managing application an indication that the first application is inactive, and receives from the managing application an indication that the second application is inactive determined in response to a second application timeout window being exceeded because of insufficient activity associated with the second application.
