+# retry logic for destroy: sometimes, a full workspace destroy does not work. This can be due to e.g.:
+# * implicit dependencies between terraform resources not declared with depends_on,
+# * unclean shutdown of resources, e.g. service does not close db connections, db still sees clients connected,
+# * GCP stuff not allowing our resources to be deleted.
+# Most of the time, retrying a destroy fixes these causes.
