-;;; Without generational GC, GC gets really slow unless we collect in
-;;; large chunks. For small chunks, efficiency tends to grow roughly
-;;; linearly with chunk size. Later we hit diminishing returns as we
-;;; approach the total amount of RAM we use, or we can even get into
-;;; performance trouble by clobbering cache and VM systems too hard.
-;;; But modern machines tend to think of 20 Mb as a moderate amount of
-;;; memory, and it's of the same order of magnitude as the amount of
-;;; RAM we need for the build, so it seems like a plausible chunk size.
