A couple times, I've seen tests fail in the gate because we got back a
404 while trying to clean out the test account. The story that gets us
here seems to be:
- One or more object servers take too long to respond to the initial
DELETE request, so the test client gets back a 503 and sleeps so
it can retry.
- Meanwhile, the servers finish writing their tombstones and want to
respond 204 (but probably *actually* respond 408 because the proxy
killed the connection).
- The test client sends its retry, and since the object servers now
have tombstones, it gets back a 404.
But the thing is, this is *outside of the test scope* anyway, we're just
trying to get back to a sane state. If it's gone, s much the better!
For an example of this, see the failures on patchset 3 of
https://review.openstack.org/#/c/534978 (which both failed for the same
reason on different tests).
