'make world' will do one thing at a time. In order to utilize more
than one CPU, you'll need to run 'make world -j2'. This runs two
concurrent makes. In fact, it tends to work better with -j4.

The fact that the idle processes are showing as the most active
processes is because of the weighting over a period of time. At the
time I took this snapshot, the most active processes were the C
compilers.
Note that this is not related to SMPng. If it were, I would have
referred you to -CURRENT. You shouldn't be asking questions about
-CURRENT on this mailing list.
