You can't pass the options to the Redland BDB opening, at present.

The question of transactions comes up now and then and I have
discussed it with some people in private mail, and sketched out
an API, but it's not yet been added.  The general idea is to
make it an option, and allow bulk operations while holding
a transaction handle (BDB DB_TXN, something else in MySQL).

I don't tend to add features before they are requested and
they get added faster when I get some encouragement (and patches!), 
especially for features I'm not using at present.
