- One other really bad feature of MS-Windows multitasking is that there
- is no concept of dynamic priority based scheduling. As a consequence
- background processes get a fixed percentage of cpu whether or not any
- other process (forground process) is using cpu at all. At least that
- is the way the system seems to behave whenever I have used it. OS/2's
- pre-emtive PRIORITY DRIVEN scheduler allows dynamic division of cpu's
- resources among multiple processes.
