Jen is a scientist, who was carrying a briefcase full of chemicals at the time. Jen had a heart attack on the crosswalk from the shock of almost being hit by Garrett’s car. Her briefcase hit the ground and the chemicals exploded on impact. The explosion shattered a third-floor window, injuring two accountants at their desks, Casey and Liam. Which of the following individuals can successfully sue Garrett for negligence?
Setup. A prоducer flоw pаsses 100,000 recоrds of 1 kB to а consumer flow, аnd the same job is built twice on one machine. Build 1 runs the two flows as separate processes, and the records travel through a pipe. Build 2 runs the two flows as two threads of one process, and the records sit in one shared array. Measured. Build 1 made 200,000 system calls to move the records, and it took 0.107 seconds. Build 2 made no system calls to move them, and it took 0.040 seconds. Question. In build 1, what do the two calls per record do?
