No, the race condition is still there; the window is just much
smaller.  The getdents() call will return a filename, which you then
stat().  But then you have to use the filename again when you
unlink().  The problem with filenames is that they're sort of
ephemeral; they're not guaranteed to not point to a different file
from the last time you used them.
