o   Make sure to mask off timer1 interrupts. It's not necessarily
    masked-off by the firmware.
o   In DELAY(). Make sure we have an inner-loop body that the compiler
    cannot eliminate. While timing does not have to be perfect, the
    loops must be there to have at least some notion of delay.
