What's the simplest method to convert YAML to dot-separated strings in Ruby?

So this:

root:
  child_a: Hello
  child_b:
    nested_child_a: Nesting
    nested_child_b: Nesting Again
  child_c: K

To this:

{
  "ROOT.CHILD_A" => "Hello",
  "ROOT.CHILD_B.NESTED_CHILD_A" => "Nesting",
  "ROOT.CHILD_B.NESTED_CHILD_B" => "Nesting Again",
  "ROOT.CHILD_C" => "K"
}

I have code that relies heavily on yaml for cross-language serialization and while working on speeding some stuff up I noticed that yaml was insanely slow compared to other serialization methods (e.g., pickle, json).
