lwatch.c
              Goal of the program: Run a child, and
              stop that child whenever load is above a
              given threshold. You can run int with -v,
              which makes it much more chatty. You
              can give an load-value on the
              command-line. The value checked is the 5
              minute-load, as seen by uptime, and it is
              checked every minute.
              A good test might be 'lwatch -v -l 1.2
              /bin/sleep 200'
