/** @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.
