No clue! I'm not sure it'd have to change the current API, except
changing the semantics of EAGAIN (loosening them), and adding the
non-blocking pump call. I haven't looked at it closely. It seems like
most of the changes would be under the hood.

To be honest, I don't actually understand what's going wrong in the
first place. A write is partially put on the wire, and then another
keepalive/whatever packet is written in the middle of it? Or just that
gets partially written but doesn't retry and so blocks any other writes?
  No idea yet.

I applied the patches in 256 and 250, and it's better, but I can still
get it to hang up in send_existing, so they're not a complete fix.
