This class can store up to <size> frames.

The frames are marked "empty" these frames can be re-used
|
|
and filled with data.
|
|
The other queue stores "data" frames. These frames can
|
|
be dequeued and then are be passed to the "empty" queue.
|
|
|
|
Note: you need to _fill_ the empty queue with allocated frames,
|
|
after constructions. The pointers then are owned by this

class (== deleted in destructor)
