Villagers do not share food

Among the many other inventory and path-finding related problems, it would also appear that villagers  have stopped sharing food. Noticed this on my automatic carrot farm (which is now broken). I have only tested with farmers, so I cannot confirm all professions behave similarly. 

To Recreate: 

1) Place a villager in a confined space with a bed, a composter and several blocks of planted farmland. 

2) Dump 2 or 3 full stacks of food (carrots, beets, wheat, etc) and watch the (newly minted) farmer pick them up. 

3) place a second villager in the same space. 

4) wait indefinitely as you watch the greedy farmer to refuse to share any food with his starving companion.
