[Koha] How are authority records connected with biblio records ?

In my case I used this script for a maximum of around 200'000 
bibliographic records. I see in your original e-mail you wrote of 
"several million records"...

Did you see the script offers the following options? Maybe using them 
can change the observed behaviour:

--auth-limit=S ... Only process those headings which match an authority 
record that matches the user-specified WHERE clause.

--bib-limit=S ... Only process those bib records that match the 
user-specified WHERE clause.

--commit=N ... Commit the results to the database after every N records 
are processed.

Unfortunately the manpage of this script (and other scripts...) are not 
very explicit about what they are really doing. Thanks for pointing this 
out!
