The event is serialized, the event has to wait until the preroll finishes. Same
as when Basesink is waiting for the clock. Should it be a non-serialized event,
you think?

Yes, all elements that keep on to buffers need to release. If those buffers end
up in things like adapter, they have to be able to use a method to release them
from adapter etc. Like how a method was needed in arrayqueue to copy the
buffers.
