It seems to me that, while exceptions do pose a challenge for defensive
consistency, the main issue with VirtualMachineErrors is not defensive
consistency.  VirtualMachineErrors don't pose challenges to defensive
consistency that go beyond the challenges already present with other
kinds of runtime exceptions.  Rather, it seems to me that the unique
challenge that VirtualMachineErrors present is the issue of access to
non-determinism.
