Whatever's going on here isn't network-related, it's pretty clearly
triggered by making editing changes to an org buffer. It's also
unsalvageable with C-g, or this whole thing would be much simpler!
There's an ongoing thread between Daimrod and Stephen that might
actually be the same issue, I'll check that out.

Good to know, thanks!
