I mmap() large files all the time under Digital Unix, so people do do such things.
One thing I want to add to this discussion is that I think it is important for Linux to support as much 64 bit capability on 64 bit hardware as possible. Providing 64 bit capability on 32 bit hardware is a more difficult, and can be expected to take longer. However, it makes Linux look bad when Linux/Alpha or Linux/Ultrasparc can't deal with files larger than 2G.
Just my $0.02,
Jim
