> Some Beam IOs that expose the ability to turn an unbounded source into a bounded source.  
> For example, KafkaIO uses the underlying Read.from() API to specify the {{withMaxNumRecords}} and/or {{withMaxReadTime}}.  If the former is specified, the latter is silently ignored.  
> I would expect that the first stopping condition to be reached (either max records OR max duration) would stop the source.  
> The underlying implementation {{BoundedReadFromUnboundedSource}} has this logic, but it is not supported -in Read.Unbounded- or the Beam IOs that expose this feature.
