These tests were checking for fairly narrow timing windows, but were running in parallel and heavily dependent on timer and goroutine scheduling. This change eliminates unnecessary goroutines, runs the tests sequentially (dramatically shortening the timeouts to reduce the penalty of doing so), and uses timestamp comparison instead of background timers to hopefully gain some robustness from monotonic timestamps. Many of the other tests from this package would benefit from similar simplifications, which we can apply if and when we notice flaky failures or want to improve the latency of running the test.
