At the risk of this turning into a Stack Overflow thread...
It's up to the app to ask for permission to keep running. If the app is actually in the "suspend" state, it can be killed when the OS needs more resources. If it has asked for the right to keep running, it won't be killed and will run in the background. Voice recording apps are an often cited example of apps that do this. (Navigation apps and location apps are the other types.)
