Motivation: Revertd0943dcd30. Delaying the notification of writability change may lead to notification being missed. This is a ABA type of concurrency problem. Modifications: - Revertd0943dcd30. Result: channelWritabilityChange will be called on every change, and will not be suppressed due to ABA scenario.
