Actually, in heatbugs' case, nothing really bad would happen since the
application is relatively small. However, the point is that the memory
consumption is steadly rising in any (or most) swarm applications regardless
of the size of the applications.
In reality, most of non-trivial simulation applications that use swarm
lib. are expected to be "medium" to "large" in terms of memory requirements
compared to heatbug application.
As I have mentioned in my previous mail, I have managed to make "hello-world
version 03" to thrash after a day of running in my other linux machine with
16Meg. (I know its small :-).
