Kuvharwa kunoonekwa kaviri kwakachengeteka here?
Context:In-software ouinjiniya, kaviri-akaongorora nokukiya (aizivikanwawo "kaviri-akaongorora nokukiya Optimization") chinhu Software magadzirirwo muenzaniso kushandiswa kuderedza pamusoro kuwana zvechizarira nokuedza zvechizarira zvinodiwa ("kiyi zano") asati kuwana zvechizarira. Kuvharika kunoitika chete kana kuongorora kwechirongwa chekuvharika kuchiratidza kuti kuvharika kunodiwa.  Muenzaniso wacho, paunoitwa mune mimwe mitauro nemichina, unogona kuva usina kuchengeteka. Pane dzimwe nguva, kunogona kurangarirwa kuva muitiro unopesana.  Inowanzoshandiswa kuderedza kuvharira pamusoro apo pakutevedzera "usimbe initialization" mune multi-threaded zvakatipoteredza, kunyanya sechikamu Singleton muenzaniso. Lazy initialization inodzivisa initializing a value kusvikira nguva yokutanga yawanikwa.
Kuvhara kaviri kunogona kuva kusina kuchengeteka mune mamwe mamiriro ezvinhu uye dzimwe nguva kunoonekwa sechinhu chinopesana nechimiro. Zvisinei, inogona kuitwa nenzira yakachengeteka.
