Will have another look, but the failed umount was at system _shutdown_ -
not too many processes left by then I hope.

Oh come on. We've been through this. There is a difference between

1) root maliciously breaking system with cat /dev/random > /dev/mem etc.
and
2) the system responding poorly to commands root might legitimately issue

Unmounting filesystems, no matter what they are and what order I umount
them in, falls into category 2)
