  MFC scandir.c,v 1.9
  
    scandir(3) previously used st_size to obtain an initial estimate
    of the array length needed to store all the directory entries.
    Although BSD has historically guaranteed that st_size is the size
    of the directory file, POSIX does not, and more to the point, some
    recent filesystems such as ZFS use st_size to mean something else.
  
    The fix is to not stat the directory at all, set the initial
    array size to 32 entries, and realloc it in powers of 2 if that
    proves insufficient.
