This add logic, that serializes write access to single socket

for free space at peers' side.

I think you forgot to move this patch at the beginning of the series.
It's important because in this way we can backport to stable branches
easily.
About the implementation, can't we just add a mutex that we hold until
we have sent all the payload?
Re-thinking, I guess we can't because we have the timeout to deal
with...
I need to check other implementations like TCP.
Thanks,
Stefano
