/* Data may come much faster than we can process it, so we put it
* in a queue and process it at our own pace.
*
*
* The run() method fills the queue with the necessary data and then
* calls processQueue().
*
*
* The processQueue() method looks takes the first two elements in
* the queue and processes them if they are not already being taken
* care of by a previous processQueue() call – this will happen when
* data is coming in faster than it can be processed.
*
*
* If the processQueue() call is the first to see the two bottommost
* two elements, it will process them and, when finished, it will set
* the `isPending` flag of the bottommost element to `false`, thus
* letting the next call know that it has work to do.
*
*
* If the queue was empty, run() will set the `isPending` flag of its
* first element to a falsy value, thus bootstrapping the process.
