pubsub: many tests failed

[flaky-bot]

Many tests failed at the same time in this package.

• I will close this issue when there are no more failures in this package and
  there is at least one pass.
• No new issues will be filed for this package until this issue is closed.
• If there are already issues for individual test cases, I will close them when
  the corresponding test passes. You can close them earlier, if you prefer, and
  I won't reopen them while this issue is still open.

commit: e41a153
buildURL: Build Status, Sponge
status: failed

Looks like this issue is flaky. 😟

I'm going to leave this open and stop commenting.

A human should fix and close this.

When run at the same commit (e41a153), this test passed in one build (Build Status, Sponge) and failed in another build (Build Status, Sponge).

Logs say that there is a data race in streaming_pull_test.go (specifically with closing the server or client), but running go test -race -v -run=TestStreamingPullMultipleFetches -count=1000 doesn't result in any issues.

Closing for now since it might be a one off flake.
