> Constraints
>
> Applictions that use a BDB XA resource manager must now take into account the

>
> * No in-memory logging.
> * No application-level child transactions.
> * All database-level operations (open, close, create and the like) must
> be performed outside of a global transactions (i.e., they can be performed in
> local BDB transactions, but not while a distributed XA transaction is active).
> * Environment configuration must be done using a DB_CONFIG file.
> * Cursors must be closed before a service invocation returns.
>
> New Flag
>
> * DB_XA_CREATE - This flag is passed to db_create() to create a DB handle
> that supports XA transactions.
>
> Modified Function
>
> * DB->stat() now returns the field DB_TXN_STAT->DB_TXN_ACTIVE->xa_status,
> which contains information on the XA transactions.

So now we only need work-around code for 4.7, 4.8, 5.0, & 5.1.
