I'll try, when have a bit of spare time, but I would not promise anything.
The described scenario is used in almost an every client/server application.

Here is a short description of what is going on:

Client forks and execs server. Server creates unix domain socket, does fork()
and after all preparations calls accept() on it.

Client then creates socket and calls connect() on it. Right after successful
return from connect(), client does fcntl(fd, F_SETFD, 1). Right after fcntl()
server gets error from accept(). If client calls fcntl() *before* connect(),
all goes without any hitch.

Right now I can't help with something more. Sorry again.
