exit as fast as possible
and try to rejoing as quickly as possible

Your way of Muling is primarily the reason why people lose items while transferring them. Blizzard specifically destroys games that you've left (Empty) before being in the game for about 1-5 minutes. After the game has been "Permed" (Staying in that game for over 2 or so minutes) you are safe to transfer your items quickly without the game dropping.
