Atimers just set a flag, and the function is invoked the first time
that flag is tested, which is currently at some random time after
that, depending on what the code does. So this will need to be
somehow improved to make sure we don't delay the check for too long
(or maybe it is already "good enough", I don't know).
Then there's a problem of determining which window is the problematic
one.
