Note that dealing with select() or try to overcome the limitation via
epoll() directly via the application is not a good practice (or it's not

It's suggested to use building blocks provided by glib, e.g the main
event loop[1]. That is how Qemu solve the issues of dealing with a lot
of file descriptors.
