Actually, at least Linux won't, if the object is larger than 2 GB on a 64-bit

Yeah, true.
In the end, you should always have the loop. That way, you never have to
worry about what kind of file descriptor it is, what kind of filesystem
you're running on, and what the limits of ssize_t might be.
Or if you're getting a SIGWINCH in the middle of it.
Any POSIX system will interrupt the transfer and return a short read on
receiving a signal.
