/**
 * @class Malloc_Allocator
 *
 * @brief It is a straight forward STL allocator which uses internally
 * malloc/free for its memory management. We use this allocator to be
 * independent from new/delete allocations -- and more importantly: we
 * must be independent of STL internal pooling and mutexing. 
 *
 * As an example of the problems, that could occur: 
 *
 * @arg STL container locks the global memory pool.
 * @arg STL container requires memory beyond the available pool size
 * @arg .. pool calls new
 * @arg .. .. Allocation_Database_Implementation has to register the allocation
 * @arg .. .. .. its underlying STL container have to allocate memory
 * @arg .. .. .. .. attempts to _lock_ the global memory pool (DEADLOCK)
 *
 * Thus we use this alloctor for internal containers.
