Back when the RST semi-blind attacks came out, I double-checked our ICMP
code for the same condition. It turns out that this was fixed by one of
our developers years and years ago. I can't recall the exact version of
the change now, but I believe it occured around 4.1 or 4.2.

So, it could use some quick review, but I think we're good here.
