> After the following scenario, the first record of region is skipped, without
> being sent to Mapper:
> - the reader is initialized with TableRecordReader.init()
> - then nextKeyValue is called, causing call to scanner.next() - here
> ScannerTimeoutException occurs
> - the scanner is restarted by call to restart() and then *two* calls to
> scanner.next() occur, causing we have lost the first row
