 This may be tangled up with bug #10232.

 I'm running a fake NTP server so I can monitor the clock over the net.
 The XO occasionally stops responding with the WiFi LED off.

 If I wait for that to happen and then remove AC power, the CPU LED (lower
 right) doesn't go into blink mode when the system suspends.

 I'm also running a program to monitor the battery.  Since sleep doesn't
 work right when suspended, it sleeps for 1 second in a loop checking the
 time and adds another line to the log file every two minutes rounded up to
 the next wakeup.  It shows more than two minutes between log lines so I'm
 pretty sure the system is actually suspended.

 The log files contain two examples of this quirk.

 comments.txt are my comments merged with some of the battery log lines.

 The format of batstats:
   First two columns are MJD and seconds-this-day in UTC (same format as
 ntpd log files).
   3rd column is % of battery
   4th column is battery voltage
   5th column is battery current
   6th column is system clock (seconds since epoch)
