How to turn off $stdout and $stderr in Ruby

Is it possible to turn off $stdout and $stderr and not re-direct it to a file; just turn it off so it prints out nothing to anywhere?

I've already tried the following code, but it just errors with error: Invalid argument

$stderr = IO.new(0,"w")
$stdout = IO.new(0,"w")

    Your question probably needs to be marked as a dup.
