No LGTM from a valid reviewer yet. Only full committers are accepted.
Even if an LGTM may have been provided, it was from a non-committer or
a lowly provisional committer, _not_ a full super star committer.
See http://www.chromium.org/getting-involved/become-a-committer
Note that this has nothing to do with OWNERS files.

example, messages can be JavaScript dictionaries.
JavaScript doesn't really have dictionaries, just objects.

PostMessage(dictionary);
Is it worth mentioning what this will look like in JavaScript?

{
  command: next_command,
  param_int: 123,
  param_array: ['string0', 'string1']
}
