I tried to modify signal.set_wakeup_socket() to automatically make the file descriptor non-blocking. Problem: fcntl() function and O_NONBLOCK flag don't exist on Windows. Non-blocking operations are only supported for sockets...

Calling a blocking function (write()) in a signal handler will probably block the application. So I don't think that it makes sense to support files in signal.set_wakeup_fd() on Windows. I guess that nobody used this function on Windows in fact.

I can probably simplify my patch to only support sockets on Windows.
