Comment:

 From the logs, the cpu is quite free but most memory seem to be used. So I
 think it's the kernel bug that slows everything down so much that it takes
 a long time to get to OOM. This is how most memory is being used:

 Sugar shell:

 olpc     1291 15.5 21.5  71172 50824 ?        S    Oct17 698:32  |
 \_ python /usr/bin/sugar-shell

 Three activities:

 10000    1442  0.2 15.6  67912 36860 ?        S    Oct17  10:15      \_
 python /usr/sbin/rainbow-daemon
 10002    1453  0.0  9.3  43396 22076 ?        S    Oct17   0:32      \_
 python /usr/sbin/rainbow-daemon
 10004    1464  0.0 18.2  86924 42908 ?        Sl   Oct17   0:34      \_
 python /usr/sbin/rainbow-daemon

 Three services:

 olpc     1311  0.0  3.5  15388  8368 ?        S    Oct17   0:32 python
 /usr/bin/sugar-presence-service
 olpc     1315  0.0  2.6  11504  6292 ?        S    Oct17   0:36 python
 /usr/bin/sugar-shell-service
 olpc     1319  0.0  4.3  38592 10320 ?        Rl   Oct17   0:04 python
 /usr/bin/datastore-service

 Journal:

 olpc     1330  0.0  9.8  43508 23240 ?        R    Oct17   0:34 python
 /usr/bin/sugar-activity journalactivity.JournalActivity -b
 org.laptop.JournalActivity -a 38107e5e9fc8c58743bb93f90e568ee5f7caa6fc

 So the slowness is just a red herring and the real issue is that the
 system is short of memory.

 Is 8.2 supposed to support so many big activities at the same time?
