To maintain responsiveness, the server employs a nonblocking I/O model so requests aren't delayed by slow clients.

In the graph algorithm seminar, she proved that the set of green vertices formed a nonblocker because each vertex had at least one neighbor outside the set.

During the deployment review, the nonblockers were documented separately to avoid confusion.

All emergency exits were kept nonblocked throughout the event to ensure a safe evacuation.

The nonblockingness of the new I/O subsystem improved system throughput under heavy load.
