Wouldn't that defeat the purpose of swapping ? |
| 10 |

I was thinking about something different: trying to design |
| 12 |
applications in a more swap-friendly way, eg. keeping data thats |
| 13 |
used together in a relatively closed set of pages. Or separate |
| 14 |
heavily used data from seldomly used ones. |
| 15 |
|
| 16 |
For example, an web browser could use an own pool per window. |
| 17 |
If some window is minimized, it shouldn't have to be repainted |
| 18 |
(in theory ;-)), and everything belonging to it could potentially |
| 19 |
be swapped out together, while other (active) windows dont need |
| 20 |
data from these pages. OTOH closing an window would free the |
| 21 |
whole pool - if it's an anonymous mmap()ed region, the kernel |
| 22 |
could simply throw the pages away. |
