Bug 1090966 - The LazyLoad library should return a promise r=kgrandon

in the jsperf case, you do the same code 1000 times. Here, we do this once per application, for ~10-20 files. I don't think this is meaningful. The bottleneck is either the network or the application's callback.

(note: I made a updated testcase in http://jsperf.com/promises-overhead-in-loop/2, but the result is not different)

I can still change this back if you want to :)
