Thanks for confirming this behavior. It is distressing to me that it
happens at all. It must be some bad race condition somewhere, and
unfortunately having a non-deterministic NFS server makes is unsuitable for
production use. This is a problem for me since everything I have is
FreeBSD...

I will file a bug ticket, since I'm pretty sure at this point it is not
something special with my environment.
