When I did something similar, I passed the open socket descriptor to the 
child using environment variables.  This may not be the "easiest" or "best"
way to do it, but hey, it worked!  Essentially the parent set an environment
variable with putenv() and the child read it with getenv().  Perhaps a more
elegant method would be to pass the descriptor as an argument in the exec
call.  The default is for files and sockets to remain open over and exec so
everything should be happy.
