* outside its memory area. However, in low memory systems the overhead of
* the two pools plus the potential for unused memory in either pool is
* very undesirable.
*
* In high memory environments, this is desirable when you want to use
* the RTEMS "unlimited" objects option. You will be able to create objects
* until you run out of memory.
