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

I was referring to the code, not to the diff.
You can still diff 1.8 agains

Total space is bigger, but at least it doesn't grow unboundedly.

No, that's made it harder to see what actually changed. I suppose a

As good as 1.6?

I couldn't find exactly. The ChangeLog entry on 2006-01-04 gives some
hints about functions to look at. There's also this post:

Ah yes, it's better there. What bit is the operative fix? Both the
per-freelist min_yield adjust and the count

I'm having trouble in my charting program with the amount of heap space
allocated for cells in 1.8. It ends up allocating more and more heap
(as reported by gc-stats 'cell-heap-segments and confirmed by
mallinfo()), apparently without bound. I've got between 150k and 200k
objects according to gc-
