Another point: the standard allocation (malloc) works in general with
pages: a page will really be freed if nothing in the page is used and
very often (always ?) malloc is bad at reusing pieces of a page that
have been deallocated.

Laguage with GC always deals with that issue (never perfectly, except
for stop&copy or other copacting GC) ! Otherwise, they will fail exactly
on the situation you describe which are very common in functionnal
programs.
