I cannot reproduce this:

lapse:/tmp/cdt.nnet6607> sudo losetup -f one                           #[1,305]
lapse:/tmp/cdt.nnet6607> sudo losetup -f two                             #[306]
lapse:/tmp/cdt.nnet6607> sudo mdadm -Cn2 -l1 /dev/md0 /dev/loop[01]      #[307]
mdadm: array /dev/md0 started.
lapse:/tmp/cdt.nnet6607> sudo mdadm --set-faulty /dev/md0 /dev/loop1     #[308]
mdadm: set /dev/loop1 faulty in /dev/md0
lapse:/tmp/cdt.nnet6607> cat /proc/mdstat                                #[309]
