Backport #2473

Updated by jeremyevans0 (Jeremy Evans) almost 5 years ago

=begin 
  
  1. Run the following program on Windows (XP, haven't tried others) using Ruby 1.9.1p0: 
 
  require 'socket' 
 
  server = TCPServer.open(2000) 
  while (true) 
    socket = server.accept 
    cmd = socket.readline.chomp 
    puts cmd 
    socket.close 
  end 
 
  2. Open the task manager, add "Handles" to the columns being viewed, and observe how many handles are being used. 
 
  3. Open an irb window and execute the following lines: 
 
  > s = TCPSocket.new('localhost', 2000) 
  > s.puts('foo') 
 
  4. In the task manager, note that the number of handles used by the first process has increased. Every time you connect, three handles are added; when you write and the socket is closed, only two are released. 
 
  5. Try the same instructions using Ruby 1.8.2. All the handles are released, and there is no leak. 
 
 =end
