If you're after golang-style concurrency in python, I suggest looking at gevent. It uses "greenlets" - lightweight threads implemented in userspace - and monkey patches the standard library to do cooperative multitasking. For example, when you call socket.recv(), under the hood it will register with the event loop to be woken up when that socket is readable, then yield to allow other greenlets to run while it waits. (note this is slightly different to golang's concurrency, which works similarly but runs multiple OS threads so multiple goroutines can run at the same time) The equivalent to "go fn(1, 2, 3)" in gevent is "gevent.spawn(fn, 1, 2, 3)". Any callable can be spawned this way, you don't need to pre-register functions as "startable" like in OP's library.
