Promise.onUnhandledRejectionHandled

Promise.onUnhandledRejectionHandled(function(Promise promise) handler) -> undefined

Note: this hook is specific to the bluebird instance its called on, application developers should use global rejection events

Add handler as the handler to call when a rejected promise that was reported as "possibly unhandled rejection" became handled.

Together with onPossiblyUnhandledRejection these hooks can be used to implement a debugger that will show a list of unhandled promise rejections updated in real time as promises become handled.

For example:

var unhandledPromises = [];
Promise.onPossiblyUnhandledRejection(function(reason, promise) {
    unhandledPromises.push(promise);
    //Update some debugger UI
});

Promise.onUnhandledRejectionHandled(function(promise) {
    var index = unhandledPromises.indexOf(promise);
    unhandledPromises.splice(index, 1);
    //Update the debugger UI
});
