Comment(by dsd):

 I'm working on this. Running normal runin on 13.1.0 build 30 on my XO-4
 B1, I see a slow but clear linear decrease in free memory (calculated by
 free memory + buffers + cached, reported by the "free" command) over time.

 Plotted on a graph of free memory (kb) against time, the resultant
 straight line has a gradient of -7.40.

 Now trying to narrow this down to a specific system component. At first
 glance it does not seem to be suspend/resume related.
