Hi Vincent,

There are ongoing changes about this. Right now, the bind_proc setting
is per-frontend and I'd like to move it per-listener, so that we can
start one stats socket per process. There are some complexities in doing
this caused by the fact that the frontend has to be bound to all processes
it has listeners on, which slightly changes the way the bind-process
setting is computed. But I have established an algorithm to solve that
that I just need time to implement. After that we should be able to
benefit from a per-bind "bind-process" setting, which will then also
be available for the stats socket statements.

Regards,
Willy
