FWIW, the behavior on Android is very close to what is proposed here.
If your application exceeds the amount of available memory, it simply closes right in
front of your eyes. No explanation, nothing, it's just gone (might be different on
latest Android versions). The same thing would happen with EarlyOOM - some application
would disappear.
The analogy is not completely fair.
On Android applications are designed to be Started and Stopped by the system, and they are
supposed to save
their entire state so that when restarted nothing has apparently happened, from the point
of view of the user.
(many applications are badly written, but that's another story...)
And we are talking about background applications, on a system where only one application
is in foreground
(only very recently you can have two applications in foreground).
Finally, it is the applications that are stopped (by asking them nicely trough an event),
not general system
processes; Android would never kill a wpa_supplicant process, for example.
Android has a concept of "cache" of background applications, they are there, if
possible, just to have them
back very quickly; it is similar to how Linux keeps dirty disk content in RAM and pushes
it to disk
when RAM must be freed.
