+DigiComp.FlowSessionLock
+------------------------
+
+By default the session established by Flow is not "protected" in any way.
+This package restricts every request to load the session only, if there are no other requests having it in access currently.
+It allows to set custom pointcut which will set the session in "ReadOnly" mode, which allows concurrent requests to read, but disallows the current request to write the session.
+
+If you want to allow concurrent access somewhere, you can add your trigger pointcut in Settings.yaml like such:
+  
+    DigiComp:
+      FlowSessionLock:
+        readOnlyExpressions:
+          'AcmeLock': 'method(Acme/SuperPackage/Controller/ConcurrentController->concurrentAction())'
