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.

Thanks,
