+Subject: [PATCH] Fix test race condition.
+
+The test suite randomly fails with errors such as:
+
+~~~
+  1) Failure:
+AutoloadingTest#test_autoload_lowercase [/builddir/build/BUILD/mustache-1.1.1/usr/share/gems/gems/mustache-1.1.1/test/autoloading_test.rb:17]:
+Expected: Comments
+  Actual: nil
+~~~
+
+This happens when `test_namespaced*` test cases are executed earlier
+than the remaining test cases, because they are defining
+`view_namespace` but not cleaning up afterwards.
