> This appears to be unavoidable due to the construction of the test - the 
> amount of realtime that the thread waits is asserted to be less than one 
> second, but as the class doesn't consume a {{Ticker}} (or related way to 
> track elapsed time), we have no way of deterministically controlling that 
> value within the test.
>  
> Example failure: 
> [https://builds.apache.org/job/beam_PreCommit_Java_GradleBuild/1738/testReport/junit/org.apache.beam.sdk.io.kinesis/ShardReadersPoolTest/shouldInterruptKinesisReadingAndStopShortly/]
>  
> {{java.lang.AssertionError: Expecting: <4169L> to be less than: <1000L> at 
> org.apache.beam.sdk.io.kinesis.ShardReadersPoolTest.shouldInterruptKinesisReadingAndStopShortly(ShardReadersPoolTest.java:159)
>  at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)}}

> The test could also do with a more precise error message (it looks like too 
> many elements were received based on the error message, rather than the 
> actual "took too long" failure.
