We have released the Sarcophagus. It can be used to stop Thirst/Hunger lose. Simply click the item to open it, then sit in it. It will automatically close and you can then log off of SL without losing Thirst/Hunger. When you log back into SL you will be removed from the Sarcophagus. You can also simply lay in it without logging off if you wish. You can purchase them at the Vendors or you may use the ones provided on the SIM for free.
