Sam Steingold was talking about the large-file-warning-threshold limit,
which is soft and which defaults to 10 MB, whereas GNU Emacs's hard
512 MiB limit (on 32-bit hosts) is imposed by how fixnums are implemented.

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 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=8794#52>
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 <at> debbugs.gnu.org and ask for replies to
be sent there too, as this topic is a somewhat-separate issue.
