- INIT_HEAP_SIZE is the initial size of heap. If this much heap is
- allocated initially the heap will grow by half its current size
- each subsequent time more heap is needed.
-
- If INIT_HEAP_SIZE heap cannot be allocated initially, HEAP_SEG_SIZE
- will be used, and the heap will grow by HEAP_SEG_SIZE when more
- heap is needed. HEAP_SEG_SIZE must fit into type sizet. This code
- is in init_storage() and alloc_some_heap() in sys.c
-
- If INIT_HEAP_SIZE can be allocated initially, the heap will grow by
- EXPHEAP(heap_cells) when more heap is needed.
-
- MIN_HEAP_SEG_SIZE is minimum size of heap to accept when more heap
- is needed.
-
- INIT_MALLOC_LIMIT is the initial amount of malloc usage which will
