I've tried twice to update Lakka (a custom Linux image that runs RetroArch and emulators) on a RPi 3B with 1 gigabyte of memory (and I think no swap). Updating Lakka from the Pi itself invokes a script which downloads a file from the network to SD card storage. This should not take up unbounded amounts of memory, but seems to trigger OOM livelock or something anyway (I can't tell what it is, since the GUI and SSH session hang, and Lakka doesn't enable Alt+SysRq or TTYs for some godforsaken reason). Enabling SSH and running `watch -n1 free -h` shows a concerningly low free memory amount, and IIRC the available memory number crept downwards before the GUI and SSH session both hung simultaneously.

Terminating the GUI and performing an offline update from one SSH session while running `watch -n1 sync` avoids the hang. I haven't tried sync while leaving the GUI running.

Will Linux OOM handling ever be fixed?
