Perhaps yes. People want to run the core handler in the namespace of the crashed task. And (perhaps) even dumping to the file should use per-namespace ->root/etc. (and of course core_pattern[] should not be global, but this is another story). And there are other potential users. Say, nfsd user-mode helpers wants to have the "right" mnt (at least) namespace. But again, this all needs a lot of discussions. Even the API is not actually clear. As for implementation, we could probably even force ->child_reaper (the subnamespace's init) to fork/exec the usermode helper in this case. Or a namespace should explicitly create a thread which should do this.
