Andy,

I think we must have read the same thread... said VMS implementation also
had other problems (like updating the timestamp on the parent directory)
that broke "traditional" NFS server semantics.  I think the final consensus
was that it was not behaving correctly and needed to be fixed... I believe
they did that, although I don't know if the unlink() problem was specifically
addressed.

I believe unlink() is generally always atomic over NFS as well.
