The main reason appears to be that the size of individual segments grows

Hi,
I hopefully managed to characterize the problem. I instrumented HEAD
with the attached patch that exposes the current "min yield" of both
freelists. Then, I ran the attached script that does the following:
* at regular intervals, plot the total cell heap, alive cell heap
