Yes. Except that some people say once this problem starts, the memory
footprint starts growing very fast, and the question is why.
Also, perhaps Emacs could do something to prevent large amounts of
free memory from being trapped by a small allocation, by modifying
something in how we allocate memory.
(It is a pity that a problem which was solved decades ago by using
ralloc.c is back, and on GNU/Linux of all the platforms, where such
aspects of memory fragmentation aren't supposed to happen, and all the
malloc knobs we could perhaps use to avoid that were deprecated and/or
removed.)
