V8 Garbage Collector

I don't envy these engineers having to trace through corruptions and other issues related to moving GC's, just keeping a simple regular toy GC from blowing up can be hard enough sometimes (Maybe they have some better tools, but memory corruptions are inherently prickly to debug).

rr (https://rr-project.org/) and memory watchpoints are a godsend when it comes to analysing heap corruptions.
