I would suggest to reassign $stdout instead.  This ensures that print, 
putc et cetera won't output anything either.

---
class DevNull; def write(*args) end end

$stdout = DevNull.new
puts "This output will be discarded."
$stout = STDOUT
puts "And this one won't!"
---

You could even wrap this up in a nice helper method:

---
class DevNull; def write(*args) end end

module Kernel
  def silent
    $stdout = DevNull.new
    yield
    $stdout = STDOUT
  end
end

silent do
  puts "Nothing to see here..."
  print "... and there!"
end
---

Regards,
Matthias
