Just various relatively minor suggestions.  I didn't understand the remarks
about the importance of having 'beefier' remote machines (their raw CPU power
are not different although RAM and number of CPUs per machine differ), so I took
them out.  Instead, a made a separate point about what would have happened if
we'd used multiple-CPU clients.  I put in a reference to our gws:gws benchmark,
which drove our work.

Also,

-- Add side point about possible configurations issues and link to man pages.

-- The number 'four' (for # of hello compilations) was obtained by inspection of
   the distcc log.


Review: csilvers and fergus (at Google).

Also, fixed up the side-bar from a few non-top-level pages to be
consistent with the top-level-pages bars: compilers.html and
compared.html.
