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.
