With the mock, all callbacks are now invoked synchronously.  For example

remoting.oauth2Api.refreshAccessToken(function() {
console.log("Statement A");
})
console.log("Statement B");

that would output the following before
"Statement B"
"Statement A"

would now output
"Statement A"
"Statement B"

Would that be a problem?

We're unlikely ever to use this in mocks, since it's apps v1 only, but you're
right; it should be asynchronous.
