void longjmp3(int atfd, jmp_buf buf, int flags);
longjmp3(AT_FDCWD, buf, O_DIRECT | SA_OFFSTACK | WNOHANG);
longjumps relative to the current working directory, without using any import/export trampolines and no protections from signal delivery (so it simply scribbles everywhere if a signal happens to be delivered during the operation). However, it just returns if the jmp_buf isn't initiailized.
New jargon dropped: "lonely skill" That's a skill you have which no one understands to be useful, or maybe even a skill.
Example usage: "I know exactly how much peanut butter is necessary to eat those two stalks of celery." <blank looks> "It's a lonely skill."
