[zetafunction]

My personal experience from reading code that uses Chromium's C++ garbage collector is that that's often not true. While there might no longer be use-after-free errors, it's also no longer possible to make assertions like "object X must outlive Y" because object Y could be referenced arbitrarily and kept alive longer than expected. To get around that, objects might have an explicit shutdown step. But shutting down a large graph of objects is often fraught with peril, especially when that work can span multiple processes.
