The in the test after calling greedy ...


... calloc ends up being called and the first alloc fails however the allocator
calls `rtems_malloc_extend_handler` and that ends up in the `sbrk` call in

Should the greedy call consume all memory that could be allocated and so does
the extend handler needs to be called until it has been exhausted as well?
