| * for non-cpu cached magazine cache to provide one. It might be feasible |
| * to add cpu-cached magazine cache (which would allocate it's magazines |
| * from non-cpu-cached mag. cache). This would provide a nice per-cpu |
| * buffer. The other possibility is to use the per-cache |
| * 'empty-magazine-list', which decreases competing for 1 per-system |
| * magazine cache. |
