>+        We don't support 512MB devices anymore. This will make the simulator behave more
>+        like a real device.

>+        Factor to a function.
>+        Don't use availableMemoryGuess for the simulator value as it is not a guess.

>+        Apply the same adjustments to the simulated value too.
