Are there sigkills for streams?

My guess is that some threads might not want to die.

t = Thread.new { begin
                    puts 'do'
                    sleep 10
                    puts 'done'
                 ensure
                    loop { puts "really don't wanna die" }
                 end
               }

      

        
        
        
      

    

^ Imagine what happens if you try Thread#kill

this pesky bastard.
