nit: this no longer needs to call pFinish, as the default parallel behavior is
now synchronous. I was planning to remove it from the call below.

if you look at the android tests try bot results, it shows that 75 seconds
timeout is not enough, even though it ends up working (presumably, because it
finishes close to 75 seconds).

I up'd the time out to 90 seconds and confirmed locally it does not happen.
