Some things that were previously hard VM-level errors are now handled by interrupts. While this is relatively easy to handle, I was wanting a little more structure for the error types - so, errors that should invoke an interrupt are passed along in their own structure in a VmError::Interrupt variant. If an error is raised during the tick() phase of execution that would cause an interrupt, that interrupt is intercepted and the VM continues. The State::interrupt() function also will catch double faults and triple faults, with a triple fault being its own variant in the VmError structure (so it cannot be intercepted as an interrupt by accident).
