I don't see any LOOOOOL in your speedhack code, either.

Be sure to use write(), not a stdio function like printf(). Also be sure to write to stderr(FD 2), not stdout, since that might buffer.

Code:
write(2, "LOOOL", 5);

explain_write_or_die - write to a file descriptor and report errors SYNOPSIS
#include <libexplain/write.h> void explain_write_or_die(int fildes, const void *data, long data_size); DESCRIPTION
The explain_write_or_die function is used to call the write(2) system call. On failure an explanation will be printed to stderr, obtained from explain_write(3), and then the process terminates by calling exit(EXIT_FAILURE). This function is intended to be used in a fashion similar to the following example: ssize_t result = explain_write_or_die(fildes, data, data_size); fildes The fildes, exactly as to be passed to the write(2) system call. data The data, exactly as to be passed to the write(2) system call. data_size The data_size, exactly as to be passed to the write(2) system call. Returns: This function only returns on success. On failure, prints an explanation and exits. SEE ALSO
