In my use case, I would like to ensure that all the open documents have been synced to disk before I drop the cache (which reduces the memory used size, therefore it fastens the hibernation process). Sometimes, hibernation doesn't work properly too, for example, it can't freeze the filesystems and/or processes. D.
