Review comment:
1. if you could process the results with any computation per record, you
will get full benefits of the async page fetch offered by s3a and (soon) abfs;
at 600ms a list for 200 records on s3, that's potentially 3ms/record saving
2. If `listLocatedFileStatus()` logged @ debug the toString() value of the
iterator, the S3A FS iterator will print out its IOStats, including #of S3 list
requests and min/mean/max durations.
