[hibernate-dev] Temporary session and commit issue with manual flush mode

[Steve Ebersole]

Well these are the kind of details I was asking about with 
transactionContext()  :)

So transactionContext() is sharing too much of itself at the moment to 
use it this way.  Currently it just shares the entire 
org.hibernate.engine.transaction.spi.TransactionContext from the 
originating Session.  When the "subordinate" Session is closed it is 
closing that shared TransactionContext.  Later when the originating 
Session tries to access it we have problems.

The main question is whether we should change this up in point release. 
 Or just keep it as-is since y'all have a working approach anyway
