Hi Jason,I think the better way is notify the comparing thread and let it do the releasing. You probably need similar mechanism to notify from comparing thread to checkpoint thread.It seems that there is no available APIs in glib to notify a thread whichare run coroutine to do something (idle source ?). What about using anonymous pipe as the GPollFD to communicate between colo comparing thread and colo thread ?Any ideas ? Hailiang
Haven't thought this deeply. But I think you can try event notifier first which was designed for such kind of notification.
Thanks
