Description Frank Ch. Eigler 2021-06-15 02:44:08 UTC

Gazing at server logs, one sees a minority of clients who appear to have duplicate query traffic coming in: the same URL, milliseconds apart.  Chances are the user accidentally doubled her $DEBUGINFOD_URLS somehow, and the client library is dutifully asking the servers TWICE.  Bug #27863 reduces the pain on the servers' CPU, but dupe network traffic is still being paid.  We should reject sending outright duplicate concurrent traffic.
