Subject: changing a file inline on Windows

Here is my current method for editing files:

<code>

  filename = File.join('path', 'to', 'file')
  content = []
  File.open(filename, 'r') do |file|
    content = file.readlines
  end

  content.collect! do |line|
    line.gsub!(/six/, "half a dozen")
    line.chomp
  end

  File.open(filename, 'w') do |file|
    file.write content.join($/)
  end

</code>

This is expensive though, as it rewrites the entire file, even if only a
single word in the whole file is changed.  I'm wondering if there is a
better way to do this.
