As long as I can fall back to the old /proc files when truly
radical kernel changes happen, exposure of kernel internals
isn't a serious problem.

If I had the DWARF2 data alone, /dev/mem might be enough.
(sadly, "top" would require some major work before I'd trust it)

We did that on PTX ... walking tasklists lockless is a bitch.

It's fast. Lockless tasklist walking looks easy enough.
Find the process, grab the data, then find the process
again. If the process went away, discard the data.

I guess I'd like to have a /dev/ram-only device, for protection
against touching device memory (including AGP mem) by mistake.
It's odd that there doesn't seem to be such a device already.
Without this, I'd need to re-verify much more often.

Any problem I'm not seeing?
