Hmm, I wonder if this is all a lot of hassle for an early unlock.   
Perhaps it does make sense - as discussed on a separate email thread -  
to just stipulate that any explicit locks acquired using lock() from  
within a TX get released when the TX completes.  Much easier for all  
involved.

WDYT?
