It is _marginally_ better, especially if the file is created mode 000. It 
is still possible to lose the race, but it's far less likely than just 
doing a stat().

But I agree that requiring the rename to not clobber is probably impossible 
to do with no race, so the spec should be changed if that's a requirement.
