Why would 2M be inherently better than 1G? I realize it works for the *one particular system* that you have a specimen for, but that is not a sensible approach for architecture.
The problem remains no matter how you slice it; we need a general solution. The fact that this system was ever built reflects a number of critical failures that should be surprising but sadly are not.
