* This method is use by the Cypher runtime to cater for PERIODIC COMMIT, which allows a single query to
* periodically, after x number of rows, to commit a transaction and spawn a new one.
*
* To still keep track of the running stream after switching transactions, we need to open the new transaction
* before closing the old one. This way, a query will not disappear and appear when switching transactions.
*
* Since our transactions are thread bound, we must first unbind the old transaction from the thread before
* creating a new one. And then we need to do that thread switching again to close the old transaction.
