/**
* @class DiskThread
* @ingroup persistence
*
* @brief Implements the public API of the disk threads.
*
* The disk threads have a tiny interface as they pull messages of the disk
* queue themselves. Thus it is easy to provide multiple implementations of it.
* The diskthread implements the common functionality needed above, currently
* for the filestor manager.
