the two processes are not parent/child.  I want to have a non-root
process respond to TCP connections to a low port (okay, port 80) without
the process doing a change of UID.

I could use a system of named fifos, but then all the data would need
to go through the fifo and the accepting process each way.

What I need is a way to duplicate an open FD (such as stdin) to something
named.
