| # This is pseudocode. Adapted from https://en.wikipedia.org/wiki/Producer%E2%80%93consumer_problem | |
| # | |
| # Currrent design: | |
| # | |
| # A producer places items into a queue. | |
| # A consumer removes items from the queue. | |
| # | |
| # 1. If the queue becomes empty, the consumer sleeps; until woken up later. | |
| # 2. If the queue becomes one-more-than-empty, the producer wakes up the consumer. | |
| # 3. If the queue becomes full, the producer sleeps; until woken up later. |
