This allows specifying a %job (which is equivalent to the corresponding process group). Additionally, it improves reliability of kill from sh in high-load situations and ensures "kill" finds the correct utility regardless of PATH, as required by POSIX (unless the undocumented %builtin mechanism is used). Side effect: fatal errors (any error other than kill(2) failure) now return exit status 2 instead of 1. (This is consistent with other sh builtins, but not in NetBSD.) Code size increases about 1K on i386. Obtained from: NetBSD
