We need to design a way to allow MemoryCache to handle physical memory pressure. This could be something similar to what we do on Windows (just with a different lookup table to translate the memory % usage to the actual pressure - for this we will likely need dotnet/corefx#25617 to be implemented first). Or this could be some additional extensibility point to allow user code to communicate memory pressure back to cache.
