Coming from here: http://stackoverflow.com/questions/38248911/ruby-when-copying-streams-how-to-make-it-pass-input-characters

I don't know if the stdin is not flushing the special characters down the stack, or the leaf process stdout is not flushing upwards, but something is fishy in this:

<pre>
#!/usr/bin/env
require 'open3'                              
Open3.popen3("expect -") do |i, o, e, t|     
  Thread.start { IO.copy_stream(o, $stdout) }
  Thread.start { IO.copy_stream(e, $stderr) }
  i << "spawn bash\ninteract\nwait\nexit\n"  
  Thread.start { IO.copy_stream($stdin, i) } 
  t.value                                    
end  
#=> after executing, try "ls" and press tab
</pre>
