Don't be confused. It takes 1/1024th of the KVA space I thought it did, times the number of processes atached to the segment. Setting the sysctl reduces this overhead by getting rid of the swap mappings. You can try it. I don't expect it to work. The reason I don't expect it to work is that without the sysctl, it's allocating swappable memory, and you are never getting to the point where you are seeing any swapping, therefore it probably won't matter.
