Threading is not a model (#187)

Description

Threading is not a model

Presented by Joe Gregorio

We have many concurrency/multiprocessing capabilities at our finger tips, such as threads, processes, locks, mutexes, select, epoll, transactional memory, etc. But none of them are a model for multiprocessing, they are only tools on which you would build an implementation of such a model. So what are the models we can choose from? How would they be implemented in Python? And why may the GIL actually be a good thing?
