The per-CPU value automatically uses more memory on larger systems and less 
memory on smaller systems. It's one to one with the Google TCMalloc 
configuration parameter. I like the simplicity of that. If we used a total, I'd 
want to size the default based on the number of CPUs, which this already does.
