This should fix the OOM you're getting if you run pub from bleeding_edge. Sorry
I didn't catch this earlier. (Pub's tests mock out the version number to make
them deterministic, so they don't catch this.)

I would find it a little cleaner if you did this whenComplete inline in the
expect() call.

I tried that, but it looked weird to me jammed in there. It's really clean up
code and not part of the expectation.
