Why do you think it's an issue in the first place? The space allocated for a snapshot is the amount of data freed after it was created which is not also allocated elsewhere. The way this appears to work is that the space is counted towards the most recently created snapshot which the data is shared with. No data is freed when that snapshot is destroyed.
