Another point of interest -
I set the PM threshold to 5000 microseconds (default is 50000 when in 'off' state) -
Removed the USB cable (which was generating (as it is supposed to) that wake_lock) -
Let it go to sleep last night -
Woke it this morning with the following found in the kernel's message buffer:

Note that the first few messages are from when it went to sleep (I couldn't very well clear the buffer after it went to sleep
).
