"what the practical difference is between this and threading"
The biggest practical difference is synchronization-free programming. In other words event loops are already always synchronized and you can do whatever you want with shared memory knowing that no other code is going to interfere until you explicitly stop and give up control. This allows for more reliable and more complex concurrent applications with less effort.
