Yes, it is quite easy to implement asynchronous call using thread. Here 
is the code.

class AsyncHello
  def asyncHello(arg)
    puts "hello called, arg is #{arg}"
    Thread.new(arg) {|arg|  #trick: how to implement asynchronous call 
using thread
      hello(arg)
    }
  end
  def hello(arg)
    sleep 5
    puts "Hello #{arg}"
  end
end

def testasyncall
  o = AsyncHello.new
  o.asyncHello("John")
  puts "This should be displayed before hello john"
  sleep(10)
end

testasyncall

result:
hello called, arg is John
This should be displayed before hello john
Hello John


Best regards.
