They don't even touch the shared resource though. I think this picture is good for only one reason: to confuse people who are trying to understand the concepts of concurrency. I understand the concepts well it tries to visualize, but it makes a terrible job in my opinion. | |

Then puppies need to deal with lot of thing instead of actual eating (execution/doing) such as resource fighting ,starvation, bowl switching, spilling etc... | |
