Hmm, I understood the issue as the request for adding dir_fd argument to
os.listdir. openat+fdopendir+readdir+closedir+close or, in Python,
def listdir2(path, dir_fd=None):
fd = os.open(path, dir_fd)
try:
return os.listdir(fd)
finally:
os.close(fd)

os.listdir is not atomic. opendir+readdir+closedir+close or fdup
+fdopendir+readdir+closedir+close.
