Hmmm... I don't think traditional sandboxing accomplishes anything
here, because we're trying to protect against kernel bugs, not
userspace bugs, and if the kernel is compromised then you escape the
sandbox. A KVM virtual machine would solve that, certainly, but that
sounds really complicated to do? We don't have any precedent for
spinning up virtual machines to perform normal desktop operations.
Doesn't that require hardware support anyway? i.e. virtualization might
be disabled at the firmware level?
