Flaky test: leakcheck.TestCheck #8276
Description
It seems there may have been a change in the stdlib that makes WithTimeout spawn a goroutine which may still be alive when we run CheckGoroutines in this test.

We can probably just add it to

We should also tidy up these error messages here while we're here:
