1) PORTAGE_NICENESS=19" is A LOT better.
read /usr/src/linux/Documentation/sched-design.txt

here is the important part:
 batch scheduling. A significant proportion of computing-intensive tasks
   benefit from batch-scheduling, where timeslices are long and processes
   are roundrobin scheduled. The new scheduler does such batch-scheduling
   of the lowest priority tasks - so nice +19 jobs will get
   'batch-scheduled' automatically. With this scheduler, nice +19 jobs are
   in essence SCHED_IDLE, from an interactiveness point of view.


2) Maybe you need more ram?

free when you are compiling c++ stuff?
