Maybe I am the only one who finds it confusing that the spec
sometimes speaks of a "container-managed persistence context of type
SynchronizationType.(UN)SYNCHRONIZED" and sometimes just of a
"persistence context of type SynchronizationType.(UN)SYNCHRONIZED".

Actually, I am still not convinced that this addNamedQuery method on
the EMF is the way to go rather than an EMF creation callback that
allows adding of named (criteria) queries before the EMF becomes
available. In April/May the discussion seemed to me to take that
direction.
