That simple of a solution won't work either.  ReadStream>>size simply
returns readLimit which can be non-zero and still mean there is that can
be read from the stream.  I'm at a loss to say what isEmpty should mean
in the current context where the size of the stream does not necessarily
match the number of item you get if you iterate through it.
