    The code looks good, but the tests are bound to be unstable. Making the assumption that sleeps actually sleep as long as they should is often violated (seems especially on Travis).
    
    I think we need to find a better way to test this...

> FLINK-3051 introduced already a filed in the {{CheckpointConfig}} to specify a min pause between checkpoints.
> In high-load situations (big state), jobs might spend their entire time creating snapshots, not processing data. With a min pause between checkpoints, users can guarantee that there is a certain time-span the system can use for doing some actual data processing.
