Dave's analysis is certainly correct, he's done a much more thorough
analysis of the situation. I had obviously neglected to read through
the entire thread, and missed some of the analysis.
However, read IMO should not care whether I pass it a valid buffer or
not if it's at end of file, and should return success and 0 bytes read
instead. Doesn't excuse buggy code of course, but my reading of POSIX
`read' requires this behaviour.
