queue_cancel_item() is called from RtwqCancelWorkItem() and RtwqRemovePeriodicCallback(). So please add tests for MFRemovePeriodicCallback() as well and confirm it has the same behavior.

Also, I would like to see some tests to show that MFCancelWorkItem() and MFRemovePeriodicCallback() are blocking and they do wait for their callbacks to finish. For example, use MFCancelWorkItem() to cancel a work item that's already started and takes ~1s to finish really costs ~1s.
