 * Use nsPLDOMEvent to fire a DOM event that requires safe a stable DOM.
 * For example, you may need to fire an event from within layout, but
 * want to ensure that the event handler doesn't mutate the DOM at
 * the wrong time, in order to avoid resulting instability.
 * TODO: This should be renamed nsAsyncDOMEvent or something that does
 *       not include the substring "PL" that refers to the old PLEvent
 *       structure used with the old eventing system.  See bug 334573.
