Not really. Actually NOBODY reads files bigger than 2GB in a SINGLE syscall.
Such operation would lock the process for a long and eat so many resorces from the app (it should malloc 2GB.. Or use mmap which is a kernel wrap for tis in a cached way over.. But certainly mmaping more than 2GB can be problematic..mostly because of architecture (x86) limits in mmu. So u will probably end up overwritting over mmaped stuff on the same virtual memory space of the app. this is why i said it was a silly example.
