Comment(by pgf):

 testing with the following loop:
 {{{
 #!/bin/sh

 set -x

 while :
 do
         rtcwake -s 5 -m mem
 done &
 rloop=$!

 while :
 do
         sleep 1
         echo mem > /sys/power/state
 done &
 mloop=$!

 trap "kill $rloop $mloop; exit" 0 1 2 3

 wait

 }}}

 ran for about 5 hours on a B2-with-B3-ECOs, until it hit:

 {{{
