Well, on 32bit machines, the largest file you can open is 256MB or so.
In a 64bit system, the limit is much larger (so you really shouldn't see
the "Maximum buffer size exceeded" message you're seeing), but then
again, there are various places in the C code where we turn
buffer-positions into `int', so things larger than 2GB will hit bugs
sooner or later (which will manifest in various funny ways). These bugs
shouldn't be too hard to fix, but even with my 4GB machine, opening such
large files is really painful, which makes it difficult to debug.
Stefan
