Pushed with that change; we'll soon see what the buildfarm thinks.
I suspect that the provisions for EINTR and ENOSYS errors may now be
dead code, since the Linux man page for posix_fallocate mentions
neither. They're not much code though, and POSIX itself *does*
list EINTR, so I'm hesitant to muck with that.
