How can you have infinite packets to send? Does that express an app/
protocol that just generates and sends data as quickly as it can
(e.g., a ping flood)? You don't have infinite storage, so you must be
generating the packets dynamically. Constantly sampling doesn't mean
an unbounded number of outstanding packets.
