   After an offline discussion with Piotr, I realized I do not understand what 
an `Invocation` and an `Iteration` are. Piotr explained to me that within an 
`Invocation`, there might be multiple calls to the benchmarked method 
(`readFileSplit` in this case). If there are multiple invocations of the method 
within a single iteration, the second invocation did not have the latch 
properly reset, resulting in all records being emitted in the finishing stage 
of the `ContinuousFileReadingOperator`. This led to testing a different 
behaviour than the envisioned.
