:mrdocs:

Remove the least‐recently added item having the most urgent priority (lowest value) from this multi‐priority queue and load its value into the specified `item`. If this queue is empty, this method blocks the calling thread until an item becomes available. If the optionally specified `itemPriority` is non‐null, load the priority of the popped item into `itemPriority`. The behavior is undefined unless `item` is non‐null. Note this is unaffected by the enabled / disabled state of the queue.
