Yes, the test needs cd /, too. Actually the test 126 also does double
umount thanks to the _cleanup before exit and the trap command. So the
removal of the call of the _cleanup function before exit is necessary,
too.

Yes, that's also true, if the tests are interrupted and then immediately
run again the umount will fail due to the processes in background but
I'm not sure whether it is worth fixing (and if there is a good way to
fix it).
I've had bigger problems with double mount/umount in several tests
(namely: double umount - 124, 128, double mount - 129, 130). The double
umounts occur due to the use of trapped _cleanup and umount $SCRATCH_MNT
in the tests. The double mounts occur due to the use of _setup_testdir
and _scratch_mount (both of them mount $SCRATCH_MNT in the nfs case).
The problem is that I'm not sure how to fix these without any change in
the behaviour.

I suppose that at least this patch could be committed, now:
