Memory leak in the sample app

[mhmd-azeez]

Thank you very much for writing the book and the beautiful sample app. While running the sample app, I noticed that memory usage doesn't go down. Are you aware of that? Is it because of navigation stack? Can we prevent it in a ReactiveUI app?

Here is a video showing the memory leak:

Note: Sample (32 bit) is the YouIandReactiveUI sample app.
