I have checked your patch set. In our work we were originally planning to do something similar to write_rare just so we can differentiate between memory chunks that may be modified and those that will be set once and never modify. I see you are planning to do a white paper too, actually we are doing an academic paper based on our work. If you would like to collaborate, so that ROE and write_rare would integrate well from the beginning, we will be glad to do so.
