It's not that good a number, true; but it's better than the number we wer= e=20 returning, which was typically nonsense. One of the benefits of moving memory-limit to Lisp was the removal of the= bogus=20 call to sbrk. Emacs should never call sbrk, and once the portable dumper = code is=20 merged, Emacs won't ever need to call sbrk again. Yay! All things considered, I'd rather not go down the rabbit hole of trying t= o=20 improve memory-limit further, because memory-limit was a mistake in the f= irst=20 place and nobody uses it (and rightly so) and we should be deprecating it= rather=20 than trying to improve it. That being said, if you'd like to make it bett= er=20 please feel free.
