Hi

Currently, Ryu supports eventlet only. Ryu won't work if you don't use
eventlet.

By the way, I don't understand "multithreading" you mean here because every
modern programming language supports multithread. (Python, C, java...)

Old controller like also support multithreading (see, NOX-MT)

Or you mean each applications seperate into different thread? or every
switch handled by different thread?
