With the current patches in for-next including Bharath's updated
deferred close patch, I see improvements in the test runs.
I did see this warning during test generic/132 (run to Windows) in the
broad test run, but so far everything is passing for the main test
group (there are two tests to debug that fail in the azure test target
test group) that need to be debugged
