It is my understanding that this is not useful for Android 2.2 and above, since it includes its own memory management.
Android will usually keep its memory full on purpose so recently used apps are responsive.
When you load a new app, others get swapped out of memory if there is not enough room.
So is this app useful for 2.2 and above?
