Swap memory
On reset, special memory area is marked as SWAP memory : 8K on unexpanded Z88, 40K on expanded ones. This memory area is allocated to bad or ugly applications when they're entered. On exit, this memory is released by copying used swap memory to fixed memory allocated for process storage. When normal memory becomes full, this swap area can be used for other purposes.
Out-of-memory flags - one for each bank
