Okay sure.   This is fine.   That is why I suggested that if you don't like my patch, one might instead change new Python sockets to inherit the timeout / blocking setting on BSD.

However, I hope we can all agree that having the Python socket object in a different blocking / non-blocking state than the OS socket descriptor is wrong.   This is what needs to be fixed.
