I am fairly sure the problem is the akonadi/pulseaudio/gconf-helper/dcopserver
processes that are still hanging around due to the fact that the NFS mounts they
are using have gone away.

As I said remounting the NFS /home allows them to exit and allows / to then be 
remounted ro and the system shutdown.

I think there are three bugs here:
1. KDE is not waiting for all of its sessions processes to exit before
    telling init to halt the system.
2. The rc0 scripts are not making sure all processes using the NFS files
    systems have exited prior to unmounting them.
3. The rc0 final / remount ro commadn should make sure all processes have
    been killed prior to issuing the remount command. (will the kernel allow
    them to be killed when waiting on unmounted NFS ? Kernel bug ?)
