Subject: resolv-replace issue

Hi,

I am trying to get some more parallelism out of a crawler I wrote by 
using resolv-replace, but I can't seem to get it to correctly resolve 
addresses.  I tryed the following code:

require 'net/http'
require 'open-uri'
require 'resolv-replace'

Thread.abort_on_exception = true
thread = Thread.new do
  begin
    open('http://www.google.com') do |file|
      puts file.read
    end
  rescue
    puts $!
  end
end

thread = Thread.new do
  begin
    Net::HTTP.get("www.google.com", "/")
  rescue
    puts $!
  else
    puts "success"
  end
end

1.upto(50) do
  puts "ping"
  sleep 1
end

This doesn't work unless I comment out the require 'resolv-replace' 
line.  If I try it with the resolv-replace, then I get output like this:
ping
ping
ping
ping
Hostname not known: www.google.com
ping
Hostname not known: www.google.com

Any ideas why it can't resolve, yet when I use the non ruby resolver it 
works correctly.  My ruby version is:

ruby 1.8.4 (2005-12-24) [i686-darwin8.6.1]

Thanks,
Curtis
