If you have important new fields to display, then it is a problem to
find space for them.  Probably needs another screen.  The -v screen
is already very dense but only partly well-organized.  I would move
the swap stats off it first, since I haven't used swap for almost 20
years.  I also find the top lines with memory statistics almost useless.

The least useful vm fields seem to be ozfod, %ozfod, intrn and cache,
and the most useless field is still 'buf'.
