I think this is unnecessary, malloc (either the bash malloc in lib/malloc/malloc.c or the libc provided malloc) should already take care of requesting memory in page sized chunks. At least that's what I see here (morecore function): http://git.savannah.gnu.org/cgit/bash.git/tree/lib/malloc/malloc.c?h=devel&id=216e2e9b8ba21fff677cf7794ef3d9af8c91d46d#n622 Unless I'm missing something, there's nothing to gain from optimizing on top of xmalloc/malloc.
--- That's fine -- I was just reading the comment about how 4.4 changed history allocs to optimize memory reallocs and movement. So if things were fine with malloc before, I'm not sure why they were optimized within bash in 4.4...?
