Perhaps if we find ourselves doing more of these sorts of tests in the future,
we may want to make some sort of polling solution.

Yes. This is pretty ugly. The delay isn't necessary in normal usage, but I
though it would be helpful to leave in for debugging if something breaks.

You actually have the hooks to wait for the process to start:
p.onStart(callback). We should use that instead of a Timer. However, I would
prefer this code to not be necessary at all (see other comments).
