+# Multithread Save
+
+With loglevel DEBUG, the XOS synchronizers will write to the logs when a
+particular model is saved.  This tool pulls the information about object
+saves from the logs and analyzes it.  The goal is to identify potential race
+conditions caused by the same field being saved from multiple tasks, where a
+task is a sync step, event step, pull step, or model policy.
+
+For each model, the tool will print a warning if `save()` was called on a
+model that hadn't changed (it's better to use `save_if_changed()`).  For fields
+in the model that were saved from code in two or more files, it will print out
+the file paths.  The idea is that these files should be scrutinized to make
+sure the object is being updated in a safe way.
+
