Yep, I thought that was going to be a problem.  I was hoping that the
fread buffer would not impact the stream for the later read.

It ain't worth it.  To do this right, we really need user-level STREAMS
like the IOStreams in Henrik's W3C libwww.  That is basically equivalent
to replacing all stdio with SFIO stacked disciplines.  Onward to 2.0.
