Is it irony when my Powerbook goes into sleep mode due to low battery condition, 1 second before completing a shutdown command?

It was already at the point of having terminated all the processes, the finder was gone, just an empty Hokusai desktop... sleep. I swapped the battery and woke it up. I glanced at my Hokusai for ONE SECOND before the machine powered off.

I don't believe that there wasn't a single second's worth of juice left in that battery.
