I have a better idea:

 - create a "dead_mounts" namespace.
 - chain each detached mount's ->mnt_list on dead_mounts->list
 - set mnt_namespace to dead_mounts
 - export the list via proc through the usual mount list interface

The last would be a nice bonus: I've always wanted to see the list of
detached, but not-yet destroyed mounts.

Does anybody see a problem with that?
