The downside of this is that if you kill sshnpd you kill the sessions too

The counter might be that we have process rather than isolates on the srvd. So if we restart srvd we do mot drop sessions.

This ticket is for client side. For daemon side, we have not crossed that bridge yet, but I was thinking about the possibility of forking the process to achieve a single binary while still keeping sessions alive through restarts.
