The one strategy to launch memory from an app is to launch object references that the app holds, making the memory obtainable to the garbage collector. That’s with one exception: any recordsdata mmapped in without modification, corresponding to code, could be paged out of RAM if the system needs to make use of that memory elsewhere.
