Thanks Matt, so just to be crystal clear, if I'm using promises in my own
code, then I happen to have a flow that depends on fs, for example, and
since fs doesn't return or use promises, I would have to drop out of the
promises paradigm and manage that particular part of the flow control with
callbacks or something like asynch?
