I don't understand how timeout_add could be a clean substitute
for input_add. What you probably want to check is the last arg to
your handler:

Gtk::Gdk->input_add($fileno, ['read'], sub {
        my $condition = pop @_;
        if ($condition->{read}) {
                # it's safe to read
        }
});
