They are not to be called from the application but used for ensuring
that e.g. flushing seeks happen as fast as possible and shutting down
of the element (going down to READY/NULL state) is as fast as possible.

They don't necessarily flush anything, they just make sure that the
streaming thread is stopping as soon as possible.
