q promises losing unhandled exceptions

[deployable]

I've had a number of instances where I've been losing exceptions that bluebird picks up with no changes. . Not sure if you are heavily invested in q, but I find bluebird a lot better at error handling and has a few more features. Apparently it's generally faster and consumes less memory as well.

It's a little more work to convert it into straight bluebird promise's, but not much

~reproduced this on Mac OS X. Q doesn't return ENOENT errors.~ nvm! not relevant to this issue. :)
