If man arises as a tool-carrier, we will carry tools, not people.
Don't use Python to make people; make money, and not too much. Pick a
wage and you might get somewhere.
excuse me?
(Please forgive our local pet)
is "item" a list? Perhaps the *same* list as other requests? Be careful
when you put mutable objects in a queue.
And what about domain.get_item? is it a thread safe operation?
You said the model is not a global - but is it a *different* object for
each request?
