Actually... nothing is wasted. I've read that this is the best way to rebuild
the tool chain, then the applications. Sources that rely on other sources are
guaranteed to be accurately built after the second pass of "world"
I'm sorry, but what you read was simply wrong, written by somebody who
probably didn't understand how compilers, linkers, dynamic libraries,
and executables interact.
I could see _some_ value in emerge -e system followed by emerge -e
world. There can be some (very small) effects of system packages on
each other. But you are building system again when you emerge -e
world, and there is simply no reason at all to emerge -e world twice.
