+ RAMster allows RAM on other machines in a cluster to be utilized
+ dynamically and symmetrically instead of swapping to a local swap
+ disk, thus improving performance on memory-constrained workloads
+ while minimizing total RAM across the cluster. RAMster, like
+ zcache2, compresses swap pages into local RAM, but then remotifies
+ the compressed pages to another node in the RAMster cluster.
