    Not that I know of

    The standards way is asynchronous io (aio_* interfaces). That is being
    worked on

    The API isnt directly the problem. In fact you can make a fine scalable select
    by implementing


    as multiple calls giving basically the same interface that apps expected
    anyway. Take a look at the various /dev/poll experimental interfaces and
    bits of code.
