+Tests for patch_project_and_notify_users function focusing on the Redis locking mechanism
+and concurrent access patterns.
+
+These tests verify that:
+1. Sequential operations work correctly
+2. Concurrent operations are properly serialized by Redis locks
+3. Version increments are consistent and atomic
+4. Different projects don't interfere with each other
+5. Mixed concurrent operations (patches + version checks) maintain consistency
+6. Error handling during concurrent access is robust
