In a transactional memory environment, a computer-implemented method includes receiving one or more memory locations and broadcasting, by a first processor to one or more additional processors, a cross-interrogate. The cross-interrogate includes the one or more memory locations. The computer-implemented method further includes, by the one or more additional processors, receiving the cross-interrogate, not aborting any current transaction based on the cross-interrogate, and generating an indication. The indication comprises whether the one or more memory locations is in use for the current transaction by that of the one or more additional processors. The computer-implemented method further includes sending the indication from each of the one or more additional processors to the first processor and, by the first processor, combining each indication from the one or more additional processors to yield a status code and returning the status code. A corresponding computer program product and computer system are also disclosed.
