Side note: it's fairly late in the merge window, and I don't feel
comfy merging this without more testing and more people looking at it,
so I think this is a 3.10 thing. But it would be great to see ipc
people really look at the patches, and perhaps run a few real loads to
see if it's even noticeable in practice..
