Either we get them updated to the new API or we keep ports[0] around for  
compat. If we can't get rid of ports[0], I see less value in making the  
change at all since some scripts will use .source and other will use  
.ports[0], which seems pretty confusing.

Google Docs can hopefully be updated before implementations ship with  
this, but GWT might be more problematic since there may be legacy apps  
around with unknown update shedule...

I proposed setting ports to null.
