Wow, GPIO is incredibly slow on this 9600baud build. I benchmarked running digitalWrite(D5, 1) and on average it takes 80ms to execute. It'll get a lot faster than that in the future, right?
```
> s = getTime(); for (var i = 0; i < 25; i++) {
:  digitalWrite(D5, 1);
:}; e = getTime(); console.log("Seconds:" + (e-s) / 25);
Seconds:0.08226768
```
