Subject: bug#45200: [PATCH] Force Glibc to free the memory freed

malloc_trim() is very expensive relative to free(), partly because of
what it needs to do, and partly because it flushes the fastbins cache.
If you call it every, say, 1000 iterations of free, that might suffice.
Or perhaps after each GC run.
