nobody has proposed a polling process to decide the system can suspend,
what I proposed was to have idle detection decide the system can suspend,
which would mean that if you don't want the system to suspend you have to
do something to keep it from being idle.
At the time I didn't know that Android always disabled suspend for the
entire time the display was on, so I made the assumption that timouts had
to be long enough for input events to keep the system awake, which would
put them on the order of 30 seconds or longer.
If all that is wanted is to disable the suspend for the entire time the
backlight is on you don't need wakelocks, and you don't need a privilaged
thread waking up, all you need is to tell the power management system not
to suspend through the existing mechanism. you could create a new
mechanism (wakelock) to pass the same information, but what is the
advantage of doing so?
