As discussed on discord, some peripherals are naturally slow (much slower than a CPU instruction's execution time), but currently stall the CPU until completion:

  • serial port
  • disk

I'm opening this issue to discuss how to go about not having to stall the CPU, through busy bits and/or completion interrupts.
