Similar to gstcheck.harness.Harness.crankSingleClockWait, this is the function to use
if your harnessed element(s) are using more then one gst_clock_id_wait.
Failing to do so can (and will) make it racy which #GstClockID you actually
are releasing, where as this function will process all the waits at the
same time, ensuring that one thread can't register another wait before
both are released.
