I think so, too. |

You can also use a compressed swap partition in RAM via zram |
| 39 |
(Instructions: https://wiki.gentoo.org/wiki/Zram). |
| 40 |
Then your system is still responsive enough to kill chromium when you |
| 41 |
realize that your memory fills up. |
| 42 |
|
| 43 |
It should also be possible to somehow dynamically set memory quotas but |
| 44 |
I've not tried it yet. It might work via cgroups (which portage can use |
| 45 |
natively). |
