It might seems so because I'm interleaving discussion of two different 
desires: FastCGI and scalable socket servers.   If this isn't needed for 
FastCGI so much the better, but if one were to make a sort of Node.lc I 
would imagine they'd need to hand off socket connections to workers, no?

Sounds easy.  Why didn't Todd just do that back when he was exploring 
ways to use FastCGI with LC?

As or my earlier fixation on fork(), it stems from an older discussion 
of these issues here with Andre:

    As it is, FastCGI is worse than CGI for LC because with CGI we
    can answer more than one user at the same time by spawning new
    processes. With FastCGI, while the request was being processed,
    no other request would be answered. Thats not a FastCGI limitation,
    the protocol is way smarter than CGI you receive all requests on
    the same port and you're supposed to fork(). Since we have nothing
    like forking on LC, we're dead on that front.
