When do you assert that the proper handler gets called here?  Does the test fail
if the handler above doesn't get called?

[Sheridan Rawlins, 2011/07/07 23:39:23]

Good point.  As we discussed, I'll try to pull in the jsmock library in another
patch. For the time being, I'll expose the mock and check whether the function
was called once.
