Glibc 2.7 (as shipped in Ubuntu Hardy) has posix_fallocate wired up to
the fallocate system call, and ext4 supports delayed allocation as
well as preallocation. There are number of userspace applications ---
rsync, samba, and most bittorrent applications come to mind --- where
use of fallocate would be a big win.
