* that there is not enough to write the whole file, one of the 'cb'
* functions here will be called with the required space passed as a
* parameter. Users should define their own subclass of this class depending
* on how they wish to free up space. Each callback method should return true
* if the space was freed, false otherwise. This subclass should then be used
* as a parameter in StartWriting().
