   There is a behavior change in transaction with register interest. (From my understanding this behavior exists from start of the tx implementation).
   Now register interest will block transaction commit during the period of register interest -- esp. on the node performing the register interest from client. 
   The performance hit shifts from calculating filterRoutingInfo again on remote node to no transactions allowed to commit when register interest is under way.
   Also I worry about potential performance hit and even deadlock as the remote node processing register interest message can be blocked for a while (trying to get the write lock) while there are concurrent transactions.
