I'm about to submit it, just doing last build and testing round. Merged
back the changes Hugh asked in patch 1.

Also found why the list reinitialization was needed in the past; one of
the old iterations had a bug in the remount code and was cleaning the
xattrs out of the cgroup directory but not actually removing the
directory, thus new xattrs got added to a list of freed xattrs.

So I believe we're good to go.
