Nice. I worked on something like this at an internship. I wrote a Unicorn-like preload-fork multiprocess server in Ruby (for other reasons). I realized that the workload (which involved a large amount of long-lived static data on the heap) would have seen enormous memory savings, if only we weren't running with Ruby 1.9's mark-and-sweep GC algorithm that marked every object during the mark phase. I briefly experimented with turning off GC and periodically killing workers. Thankfully, in that situation, all we actually had to do was upgrade to Ruby 2.2, which does have a proper CoW-friendly incremental GC algorithm. `fork` is awesome.
