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 
portable).

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.
