We could increase GNU Emacs's hard limit from 512 MiB to 2 GiB by making --with-wide-int the default. This is Emacs bug 8794. Stefan asked in for measurements about the performance consequences of this change. I haven't gotten around to that, but will try to bump the priority. I'll CC: this to 8794@debbugs.gnu.org and ask for replies to be sent there too, as this topic is a somewhat-separate issue.
