You may be fighting buffers because you're using printf(). This keeps it in memory until it decides it's convenient to print it(usually, whenever it finds a newline). And when you fork(), you get a close-to-identical copy... So if you fork while anything's in the buffer it could even get printed twice! You might want to fflush(stdout); after you print, and before you fork(), to guarantee nothing's left in the buffers.
You can also do fprintf(stderr, "hello world\n"); to avoid it, since stderr never buffers. (it might be better to print to stderr anyway.)

gfs_pio_gets
GFS_PIO_GETS(3) GFS_PIO_GETS(3)
NAME
gfs_pio_gets - read one line
SYNOPSIS
#include <gfarm/gfarm.h>
char *gfs_pio_gets (GFS_File f, char * s, size_t size);
DESCRIPTION
gfs_pio_gets() reads one line from the file specified by the parameter gf to the buffer specified by the parameter s. You need to specify
the size of the buffer by the parameter size.
Unlike gfs_pio_getline(3), this function doesn't remove newline character at the end of the buffer. But if whole contents of the line can-
not be stored to the buffer due to its length, or if the file reaches the end without newline, there will be no newline at the end of the
buffer. In any case, one '
