In a 2 hour test, polling battery state every 5 seconds (envstat -i 5),
I'm still seeing some failures, though not as many as before:

$ sort  /tmp/battlog | uniq -c
 868 
   3         charge:     64.480 Wh (95.81%)
 297         charge:     65.610 Wh (97.49%)
 563         charge:     65.630 Wh (97.52%)
   1         charge:    412.640 Wh (613.14%)
   4         charge:    417.760 Wh (620.74%)
 819   charge state:     NORMAL
  49   charge state:   CRITICAL

Also note that it only did 868 polls; in two hours, it should have done
1440 of them if each poll took 0 time.

On my T42, powerd does notice AC adapter disconnects.
