This happens on an NFS mounted volume. The failure is reproducible with
probability 80%.
Less than 1 second after the test failed, the directory _is_ empty and
can be removed. It looks like a race condition within "rm -rf" to me:
After removing 'missing/file', you need to wait a bit until you can remove
'missing'.
