quoting from http://www.nightmare.com/medusa/

    A major design problem with select(2) is that an fd_set is
    usually of a fixed maximum size, on many operating systems
    the kernel needs to rebuilt to raise this limit; even on those
    that have dynamically adjustable limits, you still need to re-
    compile your application (because FD_SETSIZE is a macro).
