I think would be most useful if we're comparing the same configuration, one with thumb and one without.

If someone has a spare N900 and a few hours to kill, I think a good test would be:

- complete reflash including eMMC
- disable HAM auto-updates so it does not run apt worker in background while we're trying to take readings
- install CSSU (regular)
- reboot and take memory readings after X minutes uptime (to allow tracker to settle)
- install CSSU-thumb
- reboot and take memory readings after same X minutes uptime

This way we are comparing same to same.

It just so happens I have a spare N900 and maybe I'll try this if I find a few hours and someone else does not beat me to it.
