Use TimedWait everywhere to prevent hangs. I'm having a hard time reproing this hang locally -- I ran the test for several days on windows with no hangs.  So this change should prevent any individual test in this test from hanging and hopefully help provide some helpful info when it hangs again.

And since the tests won't hang anymore, I believe we can make them FLAKY.
