Have you run your tests on the stock platform (even just the emulator) to see if you are getting the behavior you expect there? There are a *lot* of potential gotchas if trying to test this behavior: running at the right oom_adj, fuzziness in the definition of "free memory", etc. I would suggest validating your test first on a known working build before using it to draw conclusions about the behavior of your own build.
