+Subject: [PATCH] Fix failure cleanup paths in ujson.dump()
+
+* Add missing dec-refs for if PyTuple_Pack() or writing the payload to
+  file fails
+
+* Add missing bailout for failed PyTuple_Pack()
+
+* Add tests for all but the PyTuple_Pack() failing (which requires
+  inducing a malloc() failure)
+
