To expand on that: I've now found that Linux, macOS, NetBSD, OpenBSD,
and illumos/OpenIndiana[1] pass that test.  I don't believe that Windows
does NFS.  That means that FreeBSD is the only one of our supported
platforms that fails.  I think we should simply document that NFS on
FreeBSD is broken, and await somebody getting annoyed enough to
fix that brokenness.

[1] Getting OpenIndiana to work under qemu is not a task for those
easily discouraged.
