Promise.onPossiblyUnhandledRejection

Promise.onPossiblyUnhandledRejection(function(any error, Promise promise) handler) -> undefined

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

Add handler as the handler to call when there is a possibly unhandled rejection. The default handler logs the error stack to stderr or console.error in browsers.

Promise.onPossiblyUnhandledRejection(function(e, promise) {
    throw e;
});

Passing no value or a non-function will have the effect of removing any kind of handling for possibly unhandled rejections.
