atf-run: ERROR: tools::fs::rmdir: Cannot remove directory: Directory not
atf-run: empty

What happens is that something is still holding files open when test
cleanup tries to remove the directory with them.  Since this is on an
NFS, the files are NOT removed silently, but instead become renamed to
.nfsXXXXXXXX and the directory cannot be removed.  Running ls -l in a
loop on the NFS server I can see:

 PS: Also, cleanup failure of a single test is probably not a good
 enough reason to abort complete ATF run.
