There was a thread about this on a mailing list in the past from Robert 
Watson who was concerned introducing the option might introduce race 
conditions; please see the archives for this.

If SO_ACCEPTCONN does not work for you, please consider submitting a 
regression test for it e.g. src/tools/regression/sockets/acceptconn so 
that someone can pick up on this.
