    That has problems if you link with a library that requires the lowest
    numbered fd semantic. I'm guessing mod_perl is such a library, if you
    have a script which spawns another process. Sure you can fix the
    library, but what happens when you're simply calling code you don't want
    to change?

    Perhaps a socket option on the listening socket would be better.

    One day this will be called "layer 5 routing" and every switch worth
    paying for will do it in hardware... :-)
