> The recent changes in GEODE-7435 in e3a31e190031f094ac3bd1517722d6bead710418 have caused a distributed deadlock when making a copy of a bucket.
> These changes flipped the value of containsRegionContentChange for PartitionMessageWithDirectReply.
> That flag controls what messages participate in a state flush operation. Now, many new messages are part of a state flush, including messages which trigger bucket creation. This causes the following distributed deadlock:
> 1. Member A is waiting for a StateFlush to finish
> 2. Member B is stuck in StateStabilizationMessage, waiting for messages to be processed
> 3. Member B is in the middle of processing some messages, which is what is holding up the StateStabilizationMessage
> 4. Some of those messages are PartitionMessageWithDirectReply messages that end up triggering createBucketAtomically. That method is blocks waiting for bucket creation in Member A to finish.
