Oh, sorry,  it's my  mistake of careless.

First without open-uri

What's your version?  No read_timeout option of the open-uri version in Ruby
1.8. But 1.9 or openuri in rubygems has.

module OpenURI
  Options = {
    :proxy => true,
    :proxy_http_basic_authentication => true,
    :progress_proc => true,
    :content_length_proc => true,
    :http_basic_authentication => true,
    :read_timeout => true,
    :ssl_ca_cert => nil,
    :ssl_verify_mode => nil,
  }
