No, they are not. We use event loops nowadays. I know, because I have done 
GUI programming using things like GTK and direct X11 calls.

Unnecessary. That’s why we have poll/epoll, as already discussed in this, 
um, thread. If the performance bottleneck is in the I/O (or in a GUI, 
waiting for the user’s next action), then threading doesn’t buy you 
anything, and just adds potential for trouble.

Surely only one thread is necessary.
