/dev/power. XXX - due to the way interrupt handling is structured we have no easy way to defer clearing the button interrupt until the sysmon callback has happened and the event is dispatched. We clear it imediately on return from the interrupt handler. This means we get an interrupt storm until the button is released, and then start to handle it. This needs to be fixed! (But with the default application for the power button does not make a user visible difference.)
