Then this is a big problem.  I expect 3.3 much sooner than that...

They are already coupled.  What I had suggested was that JBC define an 
interface/strategy against which it actually registered its synchs 
(another conceptual possibility here would be to rely on the new 
TransactionSynchronizationRegistry added in JEE5; but then we'd need to 
include it separately for pre-JEE5 environments).  Of course, standard 
JBC strategy behavior would be for it to register synchs against the 
TM.  However, as a configuration option, Hibernate could inject a 
different strategy through which it could handle registration of the JBC 
synchs such that it could then manage ordering of execution.
