If this can be fixed in a non-disruptive fashion, it would be good to 
assign to 4.0.0.next.  If we don't fix in 4.0.0.next, I would like to 
fix it soon after.  At the very best, in a clustered environment or one 
that passivates/activates the extended persistence context, extra memory 
will be used by the duplicate EMF.  Its not clear (to me), if the second 
level entity/query cache is also duplicated.  If the cache is duplicated 
(when serializing/unserializing an EntityManager), I would like to fix

> Steve, if you have a chance, please take a look at: HHH-6723 (Remove extra join from eager @OneToOne). I created a pull request at: https://github.com/hibernate/hibernate-core/pull/184. If possible, I'd like to restore the performance improvement of HHH-5109 for 3.6.8 and 4.0.0.CR5.
