- What good does it to to prevent the idle-process killer from deleting your
- process if it manages to prevent the process from doing anything in the first
- place? For most purposes, forcing an image exit is just as bad as deleting the
- process (there are, of course some exceptions; for example, if the process has
- a device allocated and you're more interested in making sure nobody else
- accesses that device than you are in having the process do any work).

- Which is, most likely, what you're really trying to avoid.

-
- And you'd be willing to have them simply force the process to exit from BACKUP?
- Sounds a bit strange to me.
