Attached is the small patch to fix the problems that I was having
earlier on today. This makes it so that accept will only get
real connections and not ones that never opened properly. It will
still get connections that are closing by the time that the accept
was called, but that's OK. Also, accept will now fail if the
implicit getpeername fails.
