This loop doesn't terminate till buf is zero length, which it will be
eventually. At that point, you've overwritten the real data you may
have gotten. So the loop is just plain wrong.

Uwe MRAB's code, since there's no promise that all the data will be
returned in a single call. Keep accumulating it as you loop.
