                        When executing system commands from PHP, what should one do to keep applications secure?

                        How can one take advantage of the time waiting for a lock during a stream access, to do other tasks using the following locking code as the base:                    

                    


                    

                                                $retval = flock($fr, LOCK_EX);                    


                    


                    


                    
                                            


                

                


                A)  Use flock_lazy() instead of flock()

                C)  Check the value of $retval to see if the lock was obtained
