Now handling bug in the nodejs file read buffer.  Duplicate records
found, but can be safely discarded if the final field of the record is
not used. (If incomplete record is passed in from the stream, it will be
partially read, and no warnings are given that it is incomplete. The
next package provided from the stream will then have the full record, so
the incomplete one can be discarded, as long as you can tell it is
incomplete.)
