Well, I'm not propsing a small block size, just a regular I/O where
you use a large block size, with the one exception being when you
catch up to the target size at the end. I was thinking there might be
something about the source iterators that caused it to be insanely
expensive or somehow even broken to ask for e.g. 1 byte.

Ah, roger.
