/**
* Using nsIContent** instead of nsIContent* is the parser deals with DOM
* nodes in a way that works off the main thread. Non-main-thread code
* can't refcount or otherwise touch nsIContent objects in any way.
* Yet, the off-the-main-thread code needs to have a way to hold onto a
* particular node and repeatedly operate on the same node.
*
* The way this works is that the off-the-main-thread code has an
* nsIContent** for each DOM node and a given nsIContent** is only ever
* actually dereferenced into an actual nsIContent* on the main thread.
* When the off-the-main-thread code requests a new node, it gets an
* nsIContent** immediately and a tree op is enqueued for later allocating
* an actual nsIContent object and writing a pointer to it into the memory
* location pointed to by the nsIContent**.
*
* Since tree ops are in a queue, the node creating tree op will always
* run before tree ops that try to further operate on the node that the
* nsIContent** is a handle to.
*
* On-the-main-thread parts of the parser use the same mechanism in order
* to avoid having to have duplicate code paths for on-the-main-thread and
* off-the-main-thread tree builder instances.)
