d8e81ae3c3 Abolishing the redundant generation to zone map in the vm arena, and replacing it with chainalloc, which allocates segments within a generation. 
Generations from different chains will no longer share the same zone sets, and will not be collected together.  To get this behaviour, use the same chain, as documented.
