fork w/o execv

[Luke Small]

I'm trying to do some operations in which I fork and the child closes and
simplifies socketpair listings and sends the simpler list of malloced file
descriptors to a function and sends ioctl data after it opens a socket. The
parent sends a short greeting to the child to show that it is ready. The
child is supposed to receive it and send back an ip4 address to the parent,
but it seems to be hung up and very busy. Any ideas?
