halley: "If you're really trying to access files larger than 9 petabytes (9*10^15 =~ 2^53) directly, using a scripting language, then I'd like to rent that time machine you're using."

Ha! I need this info for my CPAN distro, Search::Kinosearch. Since it's used to index collections of documents, the files which make up the index can grow quite large. I've been crafting workarounds which open new files every time you approach 2GB, but that's getting tiresome.

Currently, Kinosearch uses a couple DB_File tied hashes, and those work fine for files > 2 GB, but I'm replacing them with more specialized file formats using native Perl code, and I'd like to know how big I can allow these new files to grow. I'll probably store pointer data as a pair of packed network ints and multiply.

If 32-bit Perl can handle integers up to 2**53 accurately, not in native format but in the mantissa of the double, I'm golden. 9 petabytes will suffice.

Thanks,
