- The swapfile not only cannot shrink, it cannot reuse space in
- the file expanded for another app: It uses what space it can
- in the 1st 20meg, then creates a new expansion region for the
- currently running app.
-
- Overall, it keeps expanding when more is needed by the app, even
- if the file is 100 megabytes! This is why, should the swapfile
- expand, it expands to such great sizes (you'd think 100 meg
- would be enough for almost anything...).
-
- This can be demonstrated easily by running an app which
- increases the swapfile, killing the app, and running it
- again. You'll see the swapfile grow every time:

- This is a HUGE bug that NeXT apparently still hasn't addressed,
- even in 3.0. When you have to reboot your file server every couple
- of days, it gets old quickly. This is just plain poor design.
