IIRC the Linux kernel handling of CONFIG_NR_CPUS has changed: it used to
allocate potentially large static data of size proportional to
CONFIG_NR_CPUS, but has been changed recently to do that dynamically
based on the actual number of CPUs. Which is why the default can now be
set to 512 without suffering from undue blow up.

On the contrary, it seems eminently practical.
