I'm beginning to doubt that this is particularly associated with system
load (there was speculation that this is related to the scenario of wifi
APs causing NetworkManager and dbus-daemon to go crazy, slowing down the
system, which is a separate bug).

I've used the following script in /etc/init/load.conf to simulate heavy
system load:

description "load"
manual
script
 while true; do true; done &
 while true; do true; done &
 while true; do true; done &
 while true; do true; done &
 while true; do true; done &
 exec cpulimit -l 1 -c 1 -p `ps ax | grep dbus-daemon | head -n 1 | awk '{print $1;}'`
end script

And it definitely slows things down.  But I couldn't reproduce this
specific bug with that running.  I actually haven't seen it at all on my
test or daily driver devices since OTA7.  I don't know if that means it
is fixed, harder to reproduce, or I've just been lucky.

Ari, you mention seeing this a lot.  Are you on OTA7?

Bug description:
  [filing here although may be other components]

  Mako running 211 from rtm
   I experienced these symptoms which have been previously mitigated in other scenarios.
  Last week while traveling and roaming this happened pretty much 100% of the time.
  This occurred in all areas (hotel, MWC, outside, etc)

  Press power button, no response
  Press button again, screen turns on for a few seconds then turns off
  Press button again, either phone resumes or more often the power dialog is shown

  When I returned back home the function was normal without reboot or
  other changes.

  The differences in environment:
  Roaming on foreign GSM network
  Lots of Wifi APs not connected

  Attached are some perhaps relevant logs, unfortunately the syslog
  rolled.
