randomness isn't critical here anyway.


Really good randomness is a nice thing to have.  The world wouldn't end
if Nmap didn't have it though.


And here we're just talking about -iR randomness.  Nmap will still
have more secure random numbers available for other uses.

So I think the answer is that we should switch -iR to use my tweak with
3 rounds.  I'm not attaching a patch here because my testing has made a
real mess of a bunch of code and it will take me a while to clean it
up.  If there are no objections I'll check something in tomorrow.


Sounds great.  -iR is actually one of my favorite Nmap options, and
this patch makes it better.

Cheers,
-F
