**argv Rewrites (was Re: Kmem security)

[Bernd Felsche]

As an aside, I've noticed that I can't rewrite the command line
arguments under Sys V/68 R3.2.  It worked a while back under V.0.

Why would anybody want to do this? Well, simply to be able to report
what a long running or daemon process is doing by running ps.

Does the kernel now make a copy of the memory for the process and keep
a pristine version in kmem?
