this gives the right answer, but takes 70s to finish
fwiw, the time to finish doesn't make sense to me...

@only
	@async(5000)
	@it("justin test")
	sub _()
		p0 = promises.onThen(sleepPromise(0), function(res, ctx) : return ctx : end function, 0)
		p1 = promises.onThen(sleepPromise(1), function(res, ctx) : return ctx : end function, 1)
		p2 = promises.onThen(sleepPromise(2), function(res, ctx) : return ctx : end function, 2)
		p3 = promises.onThen(sleepPromise(3), function(res, ctx) : return ctx : end function, 3)
		p4 = promises.onThen(sleepPromise(4), function(res, ctx) : return ctx : end function, 4)
		all = [p4, p3, p2, p1, p0]

		promises.onThen(promises.race(all), sub(result)
			? `result=${result}`
			m.testSuite.assertEqual(result, 0)
			m.testSuite.done()
		end sub)
	end sub

note: the issue here is that my understanding of "race" is that it finishes when the first of a collection of promises finishes (asynchronously), so the expectation is that the the unit test finishes right away. Instead this took a lot of time, possibly 0s + 1s+ 2s + 3s + 4s + 60s (which is the suite timeout) = 70s. Oddly, when I shift the order of the input promises around, the test seams to finish right away. Also note that this is true for rejecting promises as well (which is what I expect).
