Here is a weird one!! My laptop (and desktop monitor) display wakes up randomly few seconds after it goes to sleep because of idle.

1. I quiesce the chrome processes, all of them using SIGSTOP (kill -STOP <pid>).
2. Turn off the display using 'xset s activate'
3. wait for it to wake...stays asleep
4. Make chrome runnable with SIGCONT signal to all chrome processes
5. Turn off the display using 'xset s activate'
6. wait for it to wake...wakes up within seconds

Repeat as many times I want.

So, fundamental question: is anyone else seeing this behavior too? I tried to close some sites like gmail, netflix, youtube etc. to see if it was limited to some websites I visit, but its not. Its the chrome browser itself. Weird!!!
