Use cooperative yields instead of sleeps to make tests more deterministic and also avoid them unnecessarily taking up test parallelism by sleeping. Yielding should have the same effect in terms of testing by exercising behavior returning `Pending` in futures, so there's no expected loss in test coverage here.

There was a problem hiding this comment.
Is the 100 here just an artifact from when we slept 100ms, or did we really need to yield 100 times (or at least more than 10 or so)?
