Correct, as far as I can tell.
It look to me as if the stack says "Hey, that is my own address" and uses
the loopback interface instead of the one associated with the address.
I have checked Mac OSX and Solaris and neither one exhibits this behavior.
I can, if requested, check {Net,Open,Free}BSD as well.
