    Fix Description: Tied arrays with DB_RECNO require a backing text file.  By
    default this goes in /var/tmp.  This can be controlled with RECNOINFO bfname.
    However, the use of arrays was killing performance.  This patch replaces
    all arrays with tied hashes.  In addition, this patch fixes the notes=U
    handling to also handle notes=U,P and notes=A,P
