I don't see an issue here as packets in the socket buffer are read and 
discarded after the address association is setup in the kernel.

Also just to say that the spec has already set expectations that connect 
would do an explicit bind ("If this channel's socket is not bound ...") 
although that is only behavior observable when running with a custom 
security manager.
