Input framework unit test adjustments.

- Generally increased the time allowed before they timeout.

- For tests w/ a clear termination condition (most of them), made
  timeouts result in a test failure.

- Seemed to be a race in some cases between tests generating output and
  the input reader stream getting removed/closed, so moved stream removal
  closer to termination time, when all output should be available.
