+/** @addtogroup XBT_mallocator
+ *  @brief The mallocator system
+ * 
+ *  This section describes the API to a mallocator.
+ *  A mallocator allows you to recycle the objects you don't need anymore
+ *  instead of freeing them. A mallocator is a stack which stores the unused objects
+ *  or a given type. If you often need to malloc() / free() objects of a certain
+ *  type, you should use a mallocator and call \a xbt_mallocator_get() and
+ *  \a xbt_mallocator_release() instead of malloc() and free(). 
+ *
+ *  When you release an object, it is not freed but it is stored
+ *  into the mallocator (unless the mallocator is full). And when you want to get a
+ *  new object, the object is just extracted from the mallocator. No malloc() is
+ *  done, unless there is no more object in the mallocator.
