schien has just created a new issue for 

== define the behavior for consecutive |getAvailability| ==
Three unclear behavior found while implementing the |getAvailability| 

1. In step 6, the same availability object is returned if an existed 
`(A, presentationUrls)` tuple is found. However, we can only return 
the same object if the requester is in the same DOM window.

2. in step 9, we should run the device monitoring algorithm in 
parallel so that we can resolve the promise as early as possible.

3. For consecutive |getAvailability| on the same `PresentationRequest`
 object, we should guarantee the resolve order in the algorithm. For 

request.getAvailability().then(function() {console.log(1)});
request.getAvailability().then(function() {console.log(2)});
should always print "12" in console for all browsers.
