test_bufferingOldest_error fails with an unexpected set of values.

Expected:
X------[12^]
Actual:
X------[1234|]
This needs to be determined if this is a valid failure or an invalid test.
Stepping through this in the debugger usually sees it succeed, which sounds like a race condition to me. I've also noticed a similar issue in TestManualClock.test_sleep(), so I wonder if the race isn't happening in there.
Actually, it seems the test_sleep() method fails most of the time when running all the tests in TestManualClock, but succeeds most of the time when running it on its own. This is all in Xcode btw (14A6270e, if that might matter).
