Does anyone know how to work with huge (2GB+) files in D2? std.stream has overflow bugs (I haven't isolated them yet) and can't return their size correctly, std.stdio.File throws a ConvOverflowError in seek() because fseek() apparently takes an int when it should take a long, and std.file only supports reading the whole file, which I can't do in 2GB address space.
It appears none of the file I/O on Phobos has been tested on huge files (until now).
