Comment(by wad):

 I'm suspecting that we might be occasionally powering the
 WLAN card back up too soon, causing the occasional failure
 to communicate after power-on.

 I'm running three experiments:
 - two machines without WLAN card, one running for 7600 cycles without a
 crash
 - two machines with the WLAN power ECO, which maintains power to the card.
 - one machine running with a 4 sec. delay before restart (instead of 80
 ms).

 So far, none have crashed.
