f719851f50 Since the dynamic generation is shared between chains (for some reason) using its unified zone set, rather than keeping a special zone set per chain, which would’ve used up more zones. 
Using arena->topGen->mortality for the dynamic generation’s mortality, rather than a global variable.

f1abe0e30f 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.
