Yes, the SDL event queue is fully thread safe, and so is Pygame code on
top of it. (Although if you are coding in C you will likely need to grab
the Python GIL to post custom events on the queue)

There are two main strategies I can think of, it may depend on the type
of game. First is simple blocked networking calls. This way the server
is idle while waiting for network data.

The other would be some sort of "get_all_events" nonblocking call where
the server could operate at a fixed framerate.
