cancel.js

//Assume we have a pipe called cars
var promise = cars.read();

//To cancel this request I can't do something like cars.cancel() since it would have no idea what I'm talking about
//I would have to do:
promise.abort();

//I'm not big on adding a bunch of code to add a cancel method to that promise which would just call abort just so I can do
promise.cancel();

makes sense
