Multiple processors, multiple processes. Multiple processes is a good
model anyways because it scales to clusters of machines.

It's probably not as expensive as having a Global Interpreter Lock
(GIL) that prevents multiple threads from running Python code at the
same time, diluting any benefits you would see from concurrent

No it can not use two reactors. Even if it could, you wouldn't get
much better performance due to the GIL.
