    1.42 +     * nodes in a way that works off the main thread. Non-main-thread code
    1.43 +     * can't refcount or otherwise touch nsIContent objects in any way.
    1.44 +     * Yet, the off-the-main-thread code needs to have a way to hold onto a
    1.45 +     * particular node and repeatedly operate on the same node.
    1.46 +     *
    1.47 +     * The way this works is that the off-the-main-thread code has an
    1.48 +     * nsIContent** for each DOM node and a given nsIContent** is only ever
    1.49 +     * actually dereferenced into an actual nsIContent* on the main thread.
    1.50 +     * When the off-the-main-thread code requests a new node, it gets an
    1.51 +     * nsIContent** immediately and a tree op is enqueued for later allocating
    1.52 +     * an actual nsIContent object and writing a pointer to it into the memory
    1.53 +     * location pointed to by the nsIContent**.
    1.54 +     *
    1.55 +     * Since tree ops are in a queue, the node creating tree op will always
    1.56 +     * run before tree ops that try to further operate on the node that the
    1.57 +     * nsIContent** is a handle to.
    1.58 +     *
    1.59 +     * On-the-main-thread parts of the parser use nsIContent* instead of
    1.60 +     * nsIContent**. Since both cases share the same parser core, the parser
    1.61 +     * core casts both to nsIContentHandle*.
