Because the work to create per namespace kernel ring buffers has not
been done. Its not clear whether a new namespace is the best approach.

/proc has not been made fully container aware. An attempt to do this
using a FUSE file system was made, but was discontinued once the
technical problems with this approach became obvious.
At the moment process ID files in /proc/ are namespace aware. The
remaining files are not.

Its the same kernel image that runs both the host and the
containers.

Same answer as 2).
Per container/per cgroup resource tracking has not been implemented.
