I repeated another deep discharge yesterday, and I'm up from 1574 to
1866 :-))

We'll see how long that game can go on before the batteris are
terminally dead ...

Another question regarding pmud: wouldn't it be a good idea to permit
pmud not shutting down the machine when it reaches 0% charge, but give
it a way to monitor the battery voltage, and run until close to battery
shutdown point?

At least for me (and I think for you too...) there's a huge difference
between the two... It would need some calibration, but the user can take
care of that. Like, an option '--end-voltage=<raw voltage reading>', and
let the user chose what to specify.

Cheers
