Then this is almost certainly the usual modus operandi of glibc, and
malloc-trim was added to Emacs precisely for these cases.  For
absolute certainty, use "M-x malloc-info" and examine the resulting
report to determine which part of the malloc arena is in the free
lists.

I see no problems here, and nothing that MPS does which we didn't see
in Emacs before.
