The most important case where this happens is during phases of creation
of large new structures (e.g. while loading a large package like Org),
where a lot of memory is allocated without generating much garbage, so
every time we run the GC that time is mostly wasted (since we don't
recover any garbage) and calling malloc_trim would also be useless in
those cases.
