I know I wrote the original version of the code. 

What I argued Nth times is that tx.suspend() should just be implemented
with 

threadLocalVariable.set(null); 

meaning that we disassociate the thread from the TX. 

The event "thread dis-association" is not relevant to anyone else, not
even to the TX.  The TX DOESN'T CARE that it is associated with n
threads or not. 

Man I really need to write that TX-lite spec.  It is a fucking mess in
your heads right now :)
