Subject: allow readdir(3) to return the same entry twice

The thing is, this really is a kernel bug. We have even bisected it (and 
it hasn't hit any released kernel). The original reporter showed it with a 
simple "rm -r".

So it really isn't a git bug, even though I initially thought it might be, 
before I looked closer.

That said, the git patch may be worth it just because two *concurrent* 
invocations of "git clean" could then cause one (or both) to fail this 
way.

Yeah, or on perhaps a buggy implementation of readdir(3) on somebody
else's system.  In either case, I just thought it might be a low impact
belt-and-suspenders fix that is worth considering.
