Some test_pages_isolated failure conditions don't include trace points.
For debugging issues caused by "pinned" pages, make sure to trace all
calls whether they succeed or fail. In this case, a failure case did not
result in a trace point. So add the missing failure case in
test_pages_isolated traces.

In which setups did you actually run into these cases?
