I think your concern has been addressed in review of various algos where base
case identification helped to avoid overhead cost in small problem sizes
relative to cache.

In light of available but not implemented better VMM algos, perhaps *BSD and
Linux could eliminate or reduce the need for:
- swap space
- swapping out RAM even if there is no lack of it
- overcommitment of memory (a bluff asking to be punished by OOM killer)
- OOM killer
Besides, they allow sloppy/dangerous programming.
