Working on this patch. I'm actually trying to understand if
during long rebases we miss something.

I think this could be a small follow up

I think I noted is that main_channel_send_item should just
be main_channel_client_send_item. It's called from a RedChannelClient
function and don't access to any MainChannel.
This would fix (partially?) one of the sensation of "split brain"
I had reviewing this patch. The message (PipeItem?) handling after the
patch is split between main-channel.c and main-channel-client.c with
allocation on one side and deallocation in another side; this make the
code a bit asymmetric.
I'll post some patches moving even this part.
I'm also quite surprised how many entities call directly MainChannelClient
functions.
In particular the MainChannel handle all bandwidth measurements. I think
this is quite wrong. There are many channels with much more bandwidth
usage that should be considered. I think RedClient should be a much
more sensible place to handle such information.
