Here we go. I think this is getting pretty clos eto being committable,
minus a bit of testing edge cases on unix (postmaster death,
disconnecting clients in various ways (especially with COPY)) and
windows (uh, does it even work at all?).

There's no large code changes in this revision, mainly some code
polishing and a good bit more comment improvements.
