Berrangé The iotest 151 creates a bunch of subprocesses, with their stdout connected to a pipe but never reads any data from them and does not gurantee the processes are killed on cleanup. This triggers resource leak warnings from python when the subprocess.Popen object is garbage collected. Signed-off-by: Daniel P.
