- Excellent idea. However, I would point out that much of what you ask
- for is already in the base operating system (in terms of the memory
- settings).
-
- The memory settings you assign to each program object are ceilings
- rather than hard and fast allocations. OS/2 2.0 automatically assigns
- the minimum amount of conventional, EMS, XMS, and DPMI memory to a
- running application. It will supply more, up to the limits you set,
- as the application requests it. But if the application only requires
- 300K conventional, it will only get that.
-
- There are also some other clever features like code sharing and demand
- paging which further improve performance in this area. You've got a
- darn smart operating system under the hood already.
