There was a problem hiding this comment.
Good catch. I have a few minor concerns.
Parallel AuTest runs can execute redirect and redirect_actions at the same time. Both tests wrote request files into the same generated data directory, so one test could overwrite the other's inputs and make redirect fail with unrelated redirect_actions requests. This gives each redirect test its own generated-data directory and keeps those directories ignored. This also makes the SIGUSR2 helper tolerate processes whose psutil cmdline is unavailable, so process scanning does not crash before signaling Traffic Server.
