A lokacin rubuta wannan rahoto, babu wani sanannen cin zarafi da ya shafi abokan cinikinmu. Koyaya, masu amfani waɗanda suka yi imanin kwamfutarsu tana cikin haɗarin haɗari na iya amfani da aikace-aikacen Terminal don ba da damar ƙarin umarnin CPU da kuma kashe fasahar Hyper-Threading da kansu, wanda zai ba da cikakkiyar kariya daga waɗannan lamuran tsaro.
