    Even if you have everything, every page, every log file, in the page
    cache, everything talking over the network wants to block.

    Will you create a thread every time tcp_sendmsg() hits the send queue

    Add some logging to tcp_sendmsg() on a busy web server if you do not
    believe me :-)

    The idea is probably excellent for operations on real files, but it's
    going to stink badly for networking stuff.
