I agree with Miguel, that you don't need specific CoRoutines support,
just use the Thread class.

Your code could be transformed in

void Update ()
     Console.WriteLine ("Starting up");
     System.Threading.Thread.Sleep(20000); // every other thread will
continue to execute
     Console.WriteLine ("20 seconds later");

"Eu poderia suportar, embora não sem dor, que tivessem
ido todos os meus amores, mas enlouqueceria se perdesse
todos os meus amigos!
A alguns deles não procuro, basta-me saber que eles existem.
Esta mera condição me encoraja a seguir em frente pela vida....
mas é delicioso que eu saiba e sinta que os adoro,  
embora não declare e não os procure sempre".
        Vinicius de Moraes - O "Poetinha"
My bad translation:
"I could survive, not without pain, that all my lovers
would disappear, but would be driven crazy if 
I had lost all my friends!
Some I don't even have to reach, I just need to know that they exist.
This mere condition makes me brave enough to go ahead with my life...
but it is sweet that I know and feel that I love them,
even if I don't state it openly and reach for them always."
        Vinicius de Moraes - Brazilian Poet
