How can you look at the u.area of another process?

In general, there's no easy way to do this since the u. is part of the
per-process information that can be swapped to disk.  The proc table
contains the information that must be resident at all times.  If you
want to read the information from the disk if it's not resident, of
course, it's possible to do what you want.
