This is really, really useful.

Helpful hint: to run the slideshow, get magicpoint (debian users: apt-get
install mgp) and do:

   mv pluto.mpg pluto.mgp # ;)
   mgp pluto.mgp -x vflib

Helpful hint #2: Actually, just gv is gets all the content.

Helpful hint #3: Actually, less pluto.mgp will do the trick (after the
rename) and lets you cut and paste the text, as I'm about to do...

Nit: "vm shrinking is not serialized with any other subsystem, it is also
threaded against itself."

The big thing I see missing from this presentation is a discussion of how
icache, dcache etc fit into the picture, i.e., shrink_caches.
