I'm not clear on why there is `ip++` in the RECORD_INST handler. We've already moved to the next instruction by running `ip++` at the end of the handler in the normal dispatch table. In the RECORD_INST handler we do the work to record the instruction but don't do the actual work of that instruction. We can't, because we only have the one handler that has to work for all instructions. Shouldn't we jump to DISPATCHER_TABLE_NORMAL without incrementing ip again?
