Joel,
That sounds good.  I haven't been watching for newer patches.

I have been working on my patch de-mangler.

It has been slow going because I have never used Lua before.
I have had it on my to-do list of things to learn for several years.

I started out just to correct indentation whitespace...

Now it also reformats bad hunk headers 
and re-writes incorrect hunk headers.

Both with informative messages to the user.  None of that:
"Malformed patch" and exit.  
Which is what the patch program does.

I have a couple more small changes to make, but it is working
pretty well now.

Given a 643,000+ line patchfile (21 Mbyte) it takes about 
10 seconds to re-write it.
With a reasonable sized patchfile, you can't even notice
it's run time.

So it has been fun, even if we don't need it for Christoph's
old patchfiles.

Mike

Adjust the parameters in /proc/sys/vm/scrub_*. And scrubd is running very
fast so its likely difficult to catch. Check /proc/meminfo to see if you
have any zeroed memory.
