Yea, so like the parallel pack-objects experiment that Nico had
done recently we decreased wall-clock time at the expense of using a
larger amount of the system resources.  That is bad as we use more
CPU time than we saved in wallclock time.  Usually a bad tradeoff,
unless you have a realtime requirement you have to meet.

It depends. If we all have 64-core processors in a few years, then it
might be a better tradeoff.

Depends.  In the experiment I did, I clearly identified flaws showing 
that the direction was bad and that another approach has to be pursued.  
Thinking in terms of 64-core processors is no excuse for bad designs.

Of course, some users might want to optimize
for wall-clock time, while others want power consumption, etc.

Better get both at the same time when possible.
