PLO is basically an "island" of its own. CDSx, transactional and CSST all mix 
and match (if I have read the PoOp correctly).

I don't have the time to read the code at the level of detail necessary to find 
this kind of flaw but mixing PLO with CDSG is definitely a recipe for the kind 
of problem you are seeing.

Look into CSST. It solved a problem for me. There is a lot of "locked" power

You *can* *not* safely intermix the use of CDSG and PLO without using special 
protocols.  This is clearly documented in the POPs.

You *can* safely intermix CDSG and transactional execution.
