Are you sure this issue is not related to the ssh-over-wifi setup or something? Because it is completely non-reproducible for me on my Paperwhite 2, also my Kindle 3 Keyboard did not have this issue either. Both(*) have/had USBNET installed and both go/went to sleep.
On the PW2, what happens if I turn the device off (pressing the power button) is the following sequence of events:
- screensaver starts
- about 1-2 minutes later, powerd is firing readyToSuspend events (counting down 10, 7, 6, 2, 1)
- ~10s after the first readyToSuspend event the device goes to mem sleep
If I see it correctly, your script triggers the mem sleep at the first readyToSuspend event (not sure this will be a good idea), so at best it saves 10s of non-mem sleep time (during which the device is idling). If you turn your device on/off 10 times a day, this saves 100 seconds of CPU and WiFi idling. I would guess this is not going to have a measurable effect.
This is tested on Kindle Paperwhite 2, firmware 5.4.3 jailbreaked, USBNET installed (but no connection via WiFi configured), USB cable plugged out (otherwise it is charging and won't sleep), WiFi on.
