$stdin isn't closed, its at the end of file.  Use #closed? to test if  
an IO has been closed or not.

$ cat test.rb
require 'net/http'
require 'io/wait'

Net::HTTP.start('www.ruby-lang.org', 80) do |http|
     body = http.get('/en/license.txt').body
end
p $stdin.closed?
p $stdin.eof?

$ ruby test.rb
false # hit ^D to close $stdin on the sending side.
true
$
$ echo hi | ruby test.rb
false
false
