This took me a little longer than I expected, mostly due to triggering an (existing) bug related to midx. So here's the series I came up with. The first patch fixes the midx bug, which otherwise causes spurious test failures in patch 3. The second patch beefs up the existing tests for the area we're touching. Patch 3 is the actual regression fix. I apologize in advance for the length of the commit message. ;) I tried to summarize all of the weird dumb-http implications I discovered. If we wanted to we could stop there for maint, and treat the rest as a separate series. But since it's cleanup with no intended behavior change, it's pretty low-risk. Patches 4-10 are mostly about cleaning up crufty interfaces that I ran across while working on the earlier patches. And then the final one is an oddity where I think the code is doing the wrong thing, but it's not possible to actually trigger the bug in practice.
