Nice. I thought of GC.addRoot several times but I was distracted by the general solution of using object lifetimes with it, so that a struct's destructor would call GC.removeRoot. For your case just pinning these and forgetting about them is the easiest way to do it.
Yes, these two must live until the end of main(). Moreover, in real (C) programs I (usually) do not create state machines on the fly, instead I keep them in pools, like RX/TX machines pools in echo-server and in echo-client.
