...we seem to have this discussion every few months... so, let's try
to squish it now before it gets too much out of hand...

Even doing what Curt suggests is bad...

	- Adds cruft to procfs.
	- Makes ps(1) depend on procfs being in the kernel
	  and /proc being mounted.
	- Requires a new file system to be mounted just to read a
	  kernel crash dump.  (Yuck!)

...if you want ps(1) to work in the absense of procfs, then you
_still_ have to keep the kmem grovelling code there.
