A normal application call might take milliseconds. An LLM call might take seconds. A streaming response might keep running while tokens are generated. An embedding pipeline might process thousands of chunks. A tool call might trigger another slow network request. And sometimes, the user is already gone. They closed the tab. They navigated...
