Testing net/http changes in ruby 1.9 and having trouble on Windows

I have managed to build Ruby 1.9 on my windows machine, but Net::HTTP calls
just hang. Here's my test script:

require 'net/http'

puts "Ruby version: #{RUBY_VERSION}"
puts "opening local site"
Net::HTTP.start("localhost", "8808") do |http|
  puts "in block"
  puts "Got response with length: #{http.get("/").body.length}"
end

puts "opening remote"

proxy = URI.parse(ENV["http_proxy"])
Net::HTTP.Proxy(proxy.host, proxy.port).start("www.google.com") do |http|
    puts "in block"
    puts "Got (proxy) response with length: #{ http.get("/").body.length}"
end

Under 1.8.5, I get this output:


>ruby test.rb
Ruby version: 1.8.5
opening local site
in block
Got response with length: 19575
opening remote
in block
Got (proxy) response with length: 4156

But under 1.9, it hangs:

>ruby19 test.rb
Ruby version: 1.9.0
opening local site
^C

Does anybody have a suggestion for what might be going on? Thanks!
