Have you tried setting

    Q.longStackSupport = true
? This is invaluable for debugging (although it does slow things down a lot, so don't use it in production)

Yep, and this is exactly why its so nice to have promises built into the language. That way, the implementing engine could provide long stack traces for them as well as extra inspection and tooling of all currently pending async operations - and it could do that at the lowest possible performance cost.
