> Batch loading data is a common use case. Often, the user would not refer to 
> the managed instances after the loading session. However, the runtime, by 
> default, spends time in detaching the managed instances by creating/removing 
> proxy or retaining state as per the configured options.
> An option should be provided to bypass these operations per persistence 
> context basis.
> AutoDetach.NONE could be a possibility. This option will be exclusive i.e. it 
> can not be specified with any other AutoDetach options. The NONE option will 
> bypass proxying the fields at the transaction boundary or close.
